Millie Bobby Brown is probably the coolest teenager person on TV right now. She's an advocate for antibullying [1], a total style icon [2], and, just like so many of us, she has an over-the-top obsession with the Kardashians [3]. If that's not enough, the Stranger Things [4] actress just sang on stage with Maroon 5 [5], proving she's got musical skills, too. And since this is Millie Bobby Brown we're talking about, she didn't just sing along to their tunes; she stood front and center on stage and casually rapped Cardi B's section of "Girl Like You" . . . and absolutely nailed it.

At just 14-years-old, one thing is for sure: if Brown decides acting isn't her thing anymore (please, no), she has a very bright future as a performer. Read on to see the video and further proof that she's one talented teen.
