Millie Bobby Brown Stood In for Cardi B at a Maroon 5 Concert, Rap Verse and All

If you ever had the chance to scroll through Millie Bobby Brown’s illustrious YouTube page, where the then-11-year-old actress posted videos of herself covering songs by Ed Sheeran, John Legend, and Adele, you might assume that her surprise performance at a Maroon 5 concert in Nashville on Sunday night was a soulful accompaniment to Adam Levine. Instead, Brown lived up to the promise she posted on her Instagram Stories from backstage at the show, that she was “about to do something epic”: She stood in for none other than Cardi B when it came time for the rapper’s verse on the song “Girls Like You”—and managed not to miss a single beat.

Brown is quite the Cardi fan girl; she saw her perform at Coachella, reacted with such disappointment to the news that she wouldn’t be meeting her at the Time 100 Gala that she literally dropped her jaw, and was part of the star-studded roster of those who made a cameo in the video for “Girls Like You”—and that was all just this past year. When she took the stage of the Bridgestone Arena over the weekend, she wore a similar ensemble to that in the video—a pair of tiny sunglasses and her now signature double buns—and also stuck with her signature enthusiasm throughout the entire verse.

That began with Cardi’s line “Not too long ago, I was dancing for dollars,” and continued up until the song finished, since Brown stuck around onstage to bounce around with Levine, after he gave her a high five. And that’s all the more impressive considering, as the 14-year-old later noted on Instagram, from her bed around 1:30 a.m., she had to wake up for school, starting off with algebra, in a matter of hours.

Before going to sleep, though, Brown naturally posted a video of the performance on Instagram, where the comments section promptly flooded with reactions like, “YAAASSSSS I’M DEAD!!!!!” (from Behati Prinsloo, who’s married to Levine); “MILLIE!!!!!!! YES” (from her Stranger Things costar Noah Schnapp); “Amazing 🙌🏼” (from Liam Payne); “Lit!!!! 🔥🔥🔥” (from Paris Hilton); and “legend” (from Hailey Baldwin. Brown also took some time to give a brief recap of the night on her Instagram Stories, noting that she “was not nervous” about performing with “such incredible people,” whom she referred to as “truly family.”

Lastly, Brown also reposted a video of herself rapping taken from the crowd, which she captioned with “imma do that again some time.” It seems like only a matter of time, then, before she pulls a similar move for another of her “dear friend[s],” Drake. (She did, after all, appear in one of his music videos just last month.)
