Actress Millie Bobby Brown and host Jimmy Fallon do some inspired musical sparring during Wednesday night's "Beat Battle."

Millie Bobby Brown just dropped the mic.

The 15-year-old star of Netflix’s “Stranger Things” totally crushed a karaoke bit with Jimmy Fallon on his show Wednesday night and we are bowing down to her.

The actress, who plays Eleven on the hit show, was tasked with coming up with songs on the fly to a beat by the show’s house band, The Roots. We’d totally expect Fallon, who is used to impromptu bits being able to do this segment but Brown held her own.

The stars hit us with song after song and Brown didn’t miss a beat and she looked like she was having a blast while doing it.

Brown stars on the upcoming third season of “Stranger Things” and Netflix dropped a new clip earlier this week. The show, which premieres July 4, centers around the lives of four adolescent boys and their friends in Hawkins, Indiana. A good portion of the show follows their adventures in another realm called the Upside Down.

The next time we do karaoke we are so inviting Brown to come along.
