Millie Bobby Brown Looks Unrecognizable as a Blonde at 'Stranger Things' S4 Premiere

Millie Bobby Brown has given herself a makeover and the 18-year-old actor almost looks unrecognizable in her new do.

On May 14, the star attended Netflix's Stranger Things Season 4 premiere in New York City with her boyfriend Jake Bongiovi. Brown walked down the red carpet in her long golden blonde locks and stunned in a Louis Vuitton white slit dress with a black sheer sleeve attached to the top, creating a one-shoulder look. Opting for a color-coordinated look, Bongiovi wore a black suit and a white turtle neck.

Brown's fellow cast members also made an appearance at the event, including David Harbour, Winona Ryder, Maya Hawke, Caleb McLaughlin, Finn Wolfhard, Sadie Sink, Noah Schnapp, Gaten Matarazzo, Charlie Heaton, Natalia Dyer and Joe Keery.

Take a closer look at the actor's new hair above. Stranger Things Season 4 will release on Netflix on May 27.
