Goodbye Blonde: Millie Bobby Brown Debuts Brand New Hair Look

Millie Bobby Brown is embracing a fresh new era, and she’s saying goodbye to being a blonde while she’s at it.

The "Stranger Things" star debuted a dramatic return to her natural brunette shade, stepping out with freshly darkened locks that marked a stylish pivot from the platinum look she unveiled earlier this year.

Millie Bobby Brown showcased the transformation at the Miami Open semi-final on Thursday, turning heads at Hard Rock Stadium alongside her husband, Jake Bongiovi, and his parents.

Wearing her hair slicked back into a polished low bun with a sharp center part, Brown added flair with a bold red ruffled hair clip. She paired the look with high-shine gold hoop earrings and retro pastel pink oval sunglasses that screamed fashion-forward.

Her outfit leaned into warm-weather sophistication, a red and white striped mini dress draped with a white cardigan over her shoulders for that effortless “off-duty starlet” vibe.

The Florence by Mills founder made it clear: she’s back to brunette, and she’s doing it her way.

The new hair comes after her surprising platinum-blonde debut in early February, which sparked comparisons to none other than pop icon Britney Spears.

Brown had taken to Instagram with a caption-free carousel showcasing her icy blonde makeover, and fans were quick to react. “BRITNEY IS COMING,” one wrote. Another commented, “Britney?! Is it you? [fire emoji].”

The speculation didn’t stop there, rumors even swirled that Brown was set to portray the Princess of Pop in an upcoming Spears biopic. Though unconfirmed, the buzz surrounding the hair color change certainly stirred conversation.

But not all the chatter was celebratory. After appearing at "The Electric State" premiere in a Pamela Anderson-inspired messy updo, Brown faced online backlash from critics claiming she looked “older than her age.” The young actress wasn’t having it.

She swiftly clapped back by sharing a screenshot of a British Vogue article titled “No One Cares How Old You Think Millie Bobby Brown Looks” on her Instagram story, adding, “@britishvogue thank you.”

Then, she took the conversation further.

In a powerful Instagram Reel, Brown addressed the scrutiny she’s faced since growing up in the public eye. “I started in this industry when I was 10 years old,” she said. “I grew up in front of the world, and for some reason, people can’t seem to grow with me.”

“I refuse to apologize for growing up,” she continued. “I refuse to make myself smaller to fit the unrealistic expectations of people who can’t handle seeing a girl become a woman.”

She also called out specific articles and journalists for targeting her appearance and choices. Headlines like “Why are Gen Zers like Millie Bobby Brown ageing so badly?” and “What has Millie Bobby Brown done to her face?” prompted her to respond directly.

“This isn’t journalism. This is bullying,” she said. “The fact that adult writers are spending their time dissecting my face, my body, my choices, it’s disturbing.”

Brown was especially critical of the female writers behind some of the articles.

“The fact that some of these articles are written by women? Even worse,” she said. “We always talk about supporting and uplifting young women, but when the time comes, it seems easier to tear them down for clicks.”

She concluded with a powerful message: “Disillusioned people can’t handle seeing a girl become a woman on her terms, not theirs.”

Millie Bobby Brown is setting the record straight, on her name and her identity.

In a recent BuzzFeed UK interview alongside her "The Electric State" co-star Chris Pratt, the 21-year-old actress revealed a surprising detail about her name: her actual middle name isn’t Bobby at all.

“It’s Millie Bonnie Brown,” she shared, adding that she swapped out Bonnie for Bobby early in her career “for sh-ts and giggles.” Pratt’s stunned response? “Oh, sh-t!”

While lighthearted in her delivery, the name Bobby wasn’t just a random choice. It appears to be a sweet nod to her father, Robert “Bobby” Brown.
