How Old Is Millie Bobby Brown? Age, Birthday & Biography

Millie Bobby Brown is 22 years old as of November 5, 2026. The British actress was born on February 19, 2004, in Marbella, Spain. She celebrated her 22nd birthday in February 2026 and will turn 23 on February 19, 2027.

For many viewers, Brown will always be associated with Eleven, the mysterious young girl introduced in Netflix’s Stranger Things. She was only 12 when the series premiered in 2016. A decade later, she has completed the show’s five-season run, starred in major films, produced projects through her family’s production company, and established a beauty business.

Her age is more than a biographical detail. It offers a useful way to understand how quickly her professional life changed, from childhood television auditions to leading and producing major Netflix films.

How Old Is Millie Bobby Brown in 2026?

Millie Bobby Brown turned 22 on February 19, 2026.

Her age is calculated from her birth date, February 19, 2004. Subtracting 2004 from 2026 gives 22, and because her birthday has already passed this year, she is currently 22.

She will remain 22 until February 18, 2027, and celebrate her 23rd birthday the following day.

Although Brown was born in Spain, she is British. Her family lived in England and the United States during her childhood, and she eventually developed her acting career through American television productions.

Millie Bobby Brown Biography: Quick Facts

Her career includes acting, film production, entrepreneurship, and advocacy. These are separate kinds of work, and her involvement in one should not automatically be assumed for every project.

What Is Millie Bobby Brown’s Real Name?

Millie Bobby Brown’s birth name is Millie Bonnie Brown.

For years, viewers knew her by her professional name, which uses Bobby as her middle name. In March 2025, during an interview with The Electric State costar Chris Pratt, Brown explained that Bonnie was her actual birth middle name.

The distinction surprised some fans because Millie Bobby Brown had already become an established entertainment name.

Following her marriage to Jake Bongiovi, she discussed another change.

In a November 2025 interview with Stranger Things costar Noah Schnapp, she explained that she was using Millie Bonnie Bongiovi.

That name reflects her publicly discussed married identity. Millie Bobby Brown remains the familiar professional name used in film credits, entertainment reporting, and audience searches.

Early Life: Before Stranger Things

Brown was born on February 19, 2004, in Marbella, Spain, to British parents Robert and Kelly Brown.

She spent part of her early childhood in England. Her family later relocated to Orlando, Florida, giving her opportunities to pursue performing professionally.

Her earliest television roles were modest rather than immediately career-defining.

In 2013, she appeared as Young Alice in Once Upon a Time in Wonderland, a fantasy series connected to ABC’s Once Upon a Time.

She was approximately nine years old when the show premiered.

The following year, she played Madison O’Donnell in Intruders, a supernatural drama shown on BBC America.

Unlike a brief guest appearance, Intruders provided a recurring storyline that required her to perform in darker dramatic material.

She also appeared in episodes of NCIS, Modern Family, and Grey’s Anatomy.

These parts gave her experience in different television formats, including crime procedurals, medical drama, and comedy.

Her family faced financial pressure while supporting her ambitions, and the Browns eventually returned to England.

The turning point came when Brown successfully auditioned for a new Netflix series about children confronting mysterious events in a fictional Indiana town.

That show was Stranger Things.

For another example of a performer who began working professionally as a child and later expanded into production, read our Melissa Joan Hart biography.

How Old Was Millie Bobby Brown When Stranger Things Started?

Millie Bobby Brown was 12 years old when Stranger Things premiered on July 15, 2016.

She played Eleven, a young girl with extraordinary powers who had grown up under the control of a secretive government laboratory.

Eleven initially communicated with relatively few words. Much of Brown’s performance depended on facial expressions, physical reactions, and her interactions with the other young actors.

The character’s vulnerability and unusual abilities became central to the show’s mystery.

Brown worked alongside Finn Wolfhard, Gaten Matarazzo, Caleb McLaughlin, Noah Schnapp, and other cast members.

As the story expanded, Eleven became more than the mysterious child introduced in the first episodes. She developed friendships, family relationships, and an increasingly complicated understanding of her own identity.

For Brown, the role provided something rare: the opportunity to portray the same major character across almost a decade of television.

Her breakthrough occurred at 12, although she had begun acting several years earlier.

Millie Bobby Brown’s Age in Every Stranger Things Season

The five seasons of Stranger Things were released over nearly ten years, making Brown’s changing age particularly noticeable.

These ages reflect the initial release of each season, not necessarily Brown’s age while filming individual episodes.

From Season 1 to Season 3

During the first three seasons, viewers watched Brown move from childhood into her mid-teenage years.

The series also changed around her.

What began as a relatively contained supernatural mystery grew into a larger story involving government experiments, family relationships, and threats from the Upside Down.

As Eleven became more independent, Brown was given opportunities to portray a wider range of emotions and relationships.

Season 4 at Age 18

Brown was 18 when the fourth season premiered on May 27, 2022.

By then, she was already working outside the series in major films.

Her performance remained important to the show’s mythology, but Stranger Things was no longer her only major professional commitment.

Season 5 at Age 21

The fifth and final season began releasing on November 26, 2025, when Brown was 21.

Netflix released additional episodes on December 25, followed by the US finale on December 31, 2025.

The finale arrived on January 1, 2026, in some international time zones, including the United Kingdom.

The series has therefore concluded as of November 2026.

There is an important difference between Eleven’s fictional age and Brown’s real age. The show’s narrative unfolds in the 1980s, and Eleven’s age within that storyline should not be confused with the actress’s age at filming or release.

Millie Bobby Brown’s Emmy Nominations

Brown’s performance in Stranger Things received recognition from the Television Academy during the show’s early years.

She earned two individual Primetime Emmy Award nominations for Outstanding Supporting Actress in a Drama Series.

Her nominations came in:

• 2017: Age 13
• 2018: Age 14

Both nominations recognized her portrayal of Eleven.

She did not win either individual award.

Receiving Emmy nominations while still in her early teens established Brown as a performer whose work was attracting attention beyond the show’s younger fan base.

Her official Television Academy profile records both nominations.

How Old Was Millie Bobby Brown in Enola Holmes?

Brown was 16 when the first Enola Holmes movie premiered on Netflix on September 23, 2020.

She portrayed Enola, the younger sister of Sherlock Holmes, in a mystery adventure based on Nancy Springer’s novels.

The character is intelligent, observant, independent, and determined to investigate situations that others expect her to avoid.

Although Enola Holmes and Stranger Things both feature young protagonists, the acting styles differ considerably.

Eleven’s earliest scenes relied heavily on restrained dialogue and emotional reactions.

Enola frequently addresses the audience, interprets clues, and drives the story through her own investigations.

The films also gave Brown a growing role behind the camera.

She worked as a producer through PCMA Productions, helping develop projects rather than contributing solely as an actress.

Enola Holmes at 16

The first film introduced the teenage detective’s search for her missing mother, played by Helena Bonham Carter.

Henry Cavill portrayed Sherlock Holmes, while Louis Partridge played Lord Tewkesbury.

For Brown, the film demonstrated that she could lead a major streaming production outside her established television franchise.

Enola Holmes 2 at 18

Enola Holmes 2 premiered on November 4, 2022.

Brown was 18.

The sequel followed Enola as she attempted to establish herself as a professional detective, investigating the disappearance of a young woman and becoming involved in a wider conspiracy.

Brown returned as both a leading performer and a producer.

Enola Holmes 3 at 22

The third film premiered on Netflix on July 1, 2026.

Brown was 22.

Directed by Philip Barantini and written by Jack Thorne, the film follows Enola to Malta, where her plans to marry Tewkesbury become complicated by the disappearance of Sherlock Holmes.

Returning performers include Louis Partridge, Henry Cavill, and Helena Bonham Carter.

The movie continued Brown’s involvement with the franchise through PCMA Productions.

Across the three releases, audiences have seen Brown portray Enola at ages 16, 18, and 22.

That progression makes the franchise a useful companion to her television career: both chart her development as a performer, but Enola Holmes also documents her expanding production responsibilities.

Godzilla Movies: Her Move Into Hollywood Blockbusters

Brown made her major live-action theatrical feature-film debut in Godzilla: King of the Monsters, released in May 2019.

She was 15.

The film placed her in a large-scale science-fiction production opposite established actors including Kyle Chandler and Vera Farmiga.

Brown portrayed Madison Russell, a teenager whose family becomes involved in events surrounding the emergence of giant creatures.

She returned as Madison in Godzilla vs. Kong, released in 2021, when she was 17.

The films introduced her to a different kind of screen production.

Where Stranger Things balanced supernatural spectacle with continuing character relationships, the Godzilla movies placed her within a franchise built around large-scale action and visual effects.

They also helped establish her theatrical career while she continued starring on television.

Damsel and The Electric State

Brown’s work in her twenties has included major Netflix films beyond the Enola Holmes franchise.

Damsel — Age 20

Damsel premiered on March 8, 2024, shortly after Brown turned 20.

She played Princess Elodie, a young woman who discovers that a proposed royal marriage conceals a deadly arrangement.

After being sacrificed to a dragon, Elodie must survive using her own judgment and resourcefulness.

Directed by Juan Carlos Fresnadillo, the film placed Brown at the center of a fantasy survival story.

She also held a producing role on the project.

That distinction matters. Serving as a producer involves professional responsibilities beyond delivering a performance, although the exact extent of those responsibilities varies by production.

The Electric State — Age 21

Brown starred alongside Chris Pratt in The Electric State, released on March 14, 2025.

She was 21.

Directed by Anthony and Joe Russo, the film presents an alternate version of the 1990s shaped by a conflict between humans and robots.

Brown portrays Michelle, a young woman traveling across the American West in search of her younger brother.

The character’s journey brings together human relationships, technology, and a dangerous postwar landscape.

By this point, Brown had accumulated substantial experience in fantasy, science fiction, mystery, and adventure films.

Her professional identity was no longer defined exclusively by Eleven.

Millie Bobby Brown’s Upcoming Movies and Shows

With Stranger Things completed and Enola Holmes 3 released, Brown has continued developing projects in new genres.

Just Picture It

Netflix announced that Brown would star alongside Gabriel LaBelle in the romantic comedy Just Picture It.

The story follows two college students whose phones unexpectedly begin displaying images of their lives ten years in the future, apparently showing them as a married couple with children.

The project is directed by Lee Toland Krieger and written by Jesse Lasky.

Brown is also involved as a producer.

The romantic comedy represents another shift in genre, moving away from the supernatural action and period mysteries associated with much of her earlier work.

An exact premiere date should only be added when confirmed by Netflix.

New Netflix Spy Drama With David Harbour

On June 26, 2026, Netflix announced an untitled spy drama featuring Brown and her former Stranger Things costar David Harbour.

The series is being written by Jack Thorne.

Harbour is set to play Matt Wolfe, a disgraced former FBI agent working as a security expert.

Brown will portray Rebecca, his estranged daughter and an FBI agent whose disappearance draws her father back into a dangerous investigation.

Both actors are attached as executive producers.

The announcement is significant because it reunites two familiar performers in a completely different relationship and dramatic setting.

No confirmed premiere date was provided in Netflix’s original announcement.

Florence by Mills: Becoming an Entrepreneur at 15

Brown launched her beauty brand, Florence by Mills, in August 2019, when she was 15.

The brand initially focused on skincare and makeup designed with younger consumers in mind.

Its name honors Brown’s great-grandmother Florence.

In interviews, Brown described developing ideas for cosmetics after spending years around professional makeup artists on film and television sets.

Rather than treating beauty products simply as a celebrity endorsement opportunity, she became involved in creating the brand’s identity and products.

In 2022, Allure reported that Brown and her family had acquired a majority stake in the company from the incubator involved in its launch.

That business development offered her and her family a greater ownership interest in the brand.

Florence by Mills forms a separate part of Brown’s professional career. Her work in cosmetics should not be confused with film production or acting income, and public information is insufficient to establish an exact current company valuation.

Millie Bobby Brown and UNICEF

In November 2018, Brown became a UNICEF Goodwill Ambassador at age 14.

UNICEF identified her as its youngest-ever Goodwill Ambassador at the time of her appointment.

Her advocacy has focused on issues affecting children and young people, including education, bullying, and opportunities for girls.

Unlike a fictional role, this position involves using her public platform to support UNICEF’s work and draw attention to children’s concerns.

Her activities have continued beyond the initial appointment.

According to UNICEF, she spoke at an event connected to the United Nations Commission on the Status of Women in 2025 and met with girls in Brazil to learn about their experiences.

These activities show a sustained public association with youth advocacy, rather than a single promotional appearance.

Further information is available through her official UNICEF Goodwill Ambassador profile.

Who Is Millie Bobby Brown’s Husband?

Millie Bobby Brown is married to Jake Bongiovi, an actor and the son of musician Jon Bon Jovi.

Their relationship became public in 2021.

The couple announced their engagement in 2023 and married in a private ceremony in May 2024.

Brown was 20 at the time.

They subsequently celebrated their marriage with family and friends in Italy later that year.

Although their relationship has received significant attention because both come from recognizable entertainment backgrounds, it is important to distinguish their public statements from rumors about their personal lives.

As of November 2026, Brown and Bongiovi are married.

Does Millie Bobby Brown Have Children?

Yes. Public reporting indicates that Brown and Bongiovi are parents to two children.

In August 2025, the couple announced that they had welcomed their first child, a daughter, through adoption.

Brown was 21 at the time.

In September 2026, they shared a public Instagram post introducing a baby boy. Brown was then 22.

PEOPLE reported, citing a source, that the couple had welcomed their second child through adoption. The couple’s public post confirmed the arrival of their son, while the additional adoption detail came through the publication’s source.

Brown has spoken publicly about her longstanding interest in adoption and building a family.

The couple has also indicated a desire to preserve privacy around their children.

For that reason, their children’s names, private records, and undisclosed personal details are unnecessary to a responsible biography.

Millie Bobby Brown’s Parents and Siblings

Brown’s parents are Robert Brown and Kelly Brown.

Her family supported her early acting opportunities during moves between Spain, England, and the United States.

She has three siblings: Paige, Charlie, and Ava Brown.

Some members of her family have participated in her professional ventures.

Her sister Paige, for example, has been associated with PCMA Productions and the earlier Enola Holmes films.

The family connection is relevant because Brown’s move into producing developed alongside a business structure involving people close to her.

However, her professional credits should be described individually rather than assuming every family member participated in every production.

How Tall Is Millie Bobby Brown?

Brown’s exact current height is not consistently established through sufficiently authoritative public measurements.

Celebrity databases frequently publish height figures, but those listings are not necessarily independently measured.

A responsible biography should avoid treating an uncertain physical measurement as a verified fact.

What Is Millie Bobby Brown’s Net Worth?

Millie Bobby Brown’s exact personal net worth has not been independently verified through complete public financial disclosures.

Her professional income may come from several areas:

• Film and television acting
• Producing and executive-producing work
• Business ownership and brand-related activities
• Commercial partnerships and licensing arrangements

However, having several sources of income does not establish a precise net worth.

The value of a private business, the revenue it generates, and the amount personally owned by its founder are different financial measurements.

Without reliable information about earnings, assets, business interests, expenses, and liabilities, an exact net-worth figure would be speculative.

Now 22, Brown has completed the television role that first defined her public image and established a film career that extends across mystery, fantasy, action, and science fiction.

Her next professional chapter will depend less on growing up alongside a familiar character and more on the projects she chooses to lead, produce, and develop as an adult.
