Charli XCX's new album BRAT has been one of her most commercially and critically successful projects in her entire career up to this point. With its highly anticipated and inescapable album rollout of bright green billboards and hit singles before its June 7th release date, Charli's new hit album is only becoming more relevant, popular, and green as "BRAT summer" comes to an end.

In a new Tik Tok video, Charli is seen walking on a sidewalk in Poland lip singing to a mashup of Fleetwood Mac's classic song "Dreams" and one of Charli's hit songs from BRAT, "360".

"i'm in poland, there's a whiff of autumn in the breeze.. something is shifting" she writes in the video text. "maybe one more remix and then ?" is the caption.

Many of her fans in the comments have been speculating on who the final mystery feature may be. Fans have brought up names like Chappell Roan, Kesha, Rosalía, and even Taylor Swift to collaborate with Charli.

Earlier this summer, Charli released a remix of her song "Girl, so confusing" with Lorde, which was actually about Lorde herself. Charli then released a remix with Billie Eilish on the song "Guess featuring Billie Eilish", which was Billie's first feature in her career. "Guess" was a song not initially on BRAT, but on the subsequent BRAT deluxe album Brat and it's the same but there's three more songs so it's not. You can listen to both remixes here:

So it seems Charli will close out BRAT summer with another remix that will surely have the internet going crazy as she says on "Girl, so confusing". As for what "and then ?" means in her TikTok caption? That's certainly anyone's "guess," but whatever she is planning will likely have her fanbase, the angels, first in line. Charli has truly been all over the pop music landscape this entire summer. She's everywhere. She's so Julia.
