Millie Bobby Brown is standing up to critics who have commented on her appearance throughout her career -- and she's making it clear she's not here for the negativity.

Brown is no stranger to trying out new things — she even changed her middle name to Bobby from Bonnie. That experimental spirit has extended to her hair through the years. Still, while she's occasionally gone blonde, like at the October 2022 premiere of Enola Holmes 2, Brown has mostly stuck to her naturally brunette hair.

For as long as the actor and star of Downton Abbey Tuppence Middleton can remember, she has had recurring unwanted intrusive thoughts that led to compulsions such as mental counting, checking and handwashing.
