Last month Charli XCX shared a photo of the three artists on set together, filming what appeared to be a new music video for a potential collaboration possibly titled "A Perfect Shape".

Charli XCX previously collaborated with Christine and the Queens on "Gone" in 2019, and worked with Polachek on her Pop 2 track "Tears" in 2017.

This afternoon (29 October) she appeared to confirm the collaboration with three words on Twitter, "charli, caroline, chris."

Charli XCX is yet to share the title of the collaboration. If it's due for release soon, it'll follow her "Good Ones" banger from last month.
