Actress Millie Bobby Brown surprised fans on Sunday night (Sept. 23) in Nashville when she appeared on stage with Maroon 5 to perform Cardi B's verse from "Girls Like You."

Sporting a denim jacket and sunglasses, the Stranger Things star didn't miss a beat as she spit Cardi's bars and even matched her energy. "I'm coming to you now doin' 20 over the limit/The red light, red light stop, stop (skrrt)/I don't play when it comes to my heart, let's get it though," she rapped.

Following her surprise performance, Brown opened up about the experience in an Instagram Stories video. "It was such an amazing night," she said. "It was such incredible people and such good friends and, you know, truly family. It's such an honor to just be on stage with such talented human beings."

The young actress also revealed she wasn't nervous at all during the performance. "In fact, I was so comfortable," she said. "It was so insane. It was so fantastic, and I had such an amazing time."

Brown is no stranger to hip-hop, having begun a friendship with Drake and even revealing the two often text. Last week, the actress claimed the rapper gives her tips about dating boys.

It's also not the first time a celebrity has been tasked with filling in for Cardi B. In July, Olympic gold medalist Chloe Kim rapped Cardi's verse on G-Eazy's "No Limit," while dancing in the crowd at an ESPY Awards after party.
