Twelve-year-old Millie Bobby Brown took the internet by storm as the mysterious Eleven on Stranger Things. She famously shaved her head for the role and is now arguably more badass than Imperator Furiosa in Mad Max: Fury Road. (Sorry, Charlize Theron.) Celebs can't stop gushing about Brown, including Aaron Paul, who recently admitted on The Tonight Show how nervous he was to interview the young actress and how he wanted to adopt her. Same.

When Brown isn't simultaneously creeping out and mesmerizing audiences, she's singing her heart out and is actually quite good. For this week's TBT, Brown shared a totally adorable video of her 5-year-old self belting out "Valerie" by Amy Winehouse.

Even as a tyke, Brown mastered the perfect combo of attitude and cuteness. Earlier this summer, she uploaded to her YouTube channel a video of herself singing Winehouse's classic jam "You Know I'm No Good." She's also sung songs by Adele, John Lennon, Birdy, and more. Like people on the internet keep saying, "In a world of tens, be an Eleven."
