Washington, Feb. 20 -- Millie Bobby Brown turned 21 on Thursday, which she celebrated in style.

The 'Stranger Things' actress took to her Instagram account to share a now-deleted video in which she showed off her platinum blonde hair and fishtail braids, reported People.

As per the publication, the video showed Brown sitting in front of a heart-shaped cake while someone placed a pair of nude sunglasses on her face. She then put a gold candle in her mouth before placing it on the cake. As someone lit the candle, Brown lip-synced the lyrics, "Except for the fact it was my birthday, my stupid birthday," from a remix of Aly & AJ's Potential Breakup Song.

Brown's husband, Jake Bongiovi, also had an adorable birthday wish for his wife.
