Millie Bobby Brown
has scored her first solo award!

The Stranger Things star took home the honor of Best Actor in a Show during Sunday's MTV Movie and TV Awards and couldn't help tearing up during her acceptance speech. Standing onstage in a glittering white dress, holding her "extremely heavy" popcorn trophy, Brown graciously thanked her fans, family members and colleagues.

Brown called the Stranger Things cast and crew "my second family" and cried while referencing her real family, thanking her mom and dad "for being so supportive." The 13-year-old closed out her speech with a few words for the Stranger Things creators.

"I want to thank the Duffer Brothers because they've created a badass female iconic character that I've got the honor to play," she said, prompting cheers from the audience. "Thank you guys so much. I love you."

Brown made another silent statement on-stage, accessorizing with an ACLU ribbon and a blue ampersand pin, signifying solidarity with GLAAD, displayed prominently on her dress.

The actress already seems to be a pro on the Hollywood circuit. Earlier this year, she gushed to ET at the SAG Awards about scoring her first movie role in the Godzilla sequel, King of Monsters, and about the intense fan reactions to her beloved Netflix series. Later that night, she and her co-stars would go on to win the award for Ensemble in a Drama Series. See the interview below.
