If you haven't watched Stranger Things then you may not know who Millie Bobby Brown is.
The child actor, 13, plays Eleven in the Netflix sci-fi drama series.
She's received wide acclaim for her role, been nominated for the Primetime Emmy Award for Outstanding Actress in a Drama Series in 2017, and a Screen Actors Guild Award for Outstanding Performance by a Female Actor in a Drama Series.
She, like many other actors and guests on the night, opted to wear black as part of the Time's Up protest.
