It's no secret that Millie Bobby Brown is a big fan of music.

From dropping lines on talkshows, to being besties with Drake, it's safe to say that she's definitely doing her best to set up a music career of her own.

But it looks like she's now just straight up replacing the top tier artists.

In a surprise guest appearance, the 14-year-old Stranger Things actress joined Maroon 5 at their Nashville concert over the weekend and she wowed the crowd with her rendition of Cardi B's verse in track "Girls Like You".

Damn, they grow up so fast.

Of course the online community were quick to step in and give their two cents on Cardi B's understudy.

What do you guys reckon, is this little pocket rocket going to drop an album soon?

Watch out Cardi!
