Millie Bobby Brown transforms in new look for 21st birthday celebration

Millie Bobby Brown rang in her 21st birthday in style, sharing a fun and sassy Instagram video to mark the milestone. The Stranger Things actress, who debuted platinum blonde hair earlier this month, rocked fishtail braids and a green bustier-style top as she celebrated in front of a heart-shaped birthday cake.

The video opened with Brown sitting at the table before someone placed nude sunglasses on her face and she put a gold candle in her mouth. As the candle was lit, she playfully mouthed the lyrics, "Except for the fact it was my birthday, my stupid birthday," from a remix of Aly & AJ’s “Potential Breakup Song.” She then dramatically lowered her sunglasses before blowing out the candle.

The couple, who tied the knot in May 2024, also celebrated their first Valentine’s Day as husband and wife earlier this month. Brown shared a romantic wedding throwback, writing, "Happy Valentine’s to the most handsome husband that’s ever lived. I love you more than anything ❤️." Bongiovi also posted a clip of the couple releasing white doves off the back of a yacht, calling it their “best moment ever.”

With love in the air and a major career ahead, Brown is stepping into her 21st year in true superstar fashion.
