It looks like Charli XCX just confirmed the Christine and the Queens and Caroline Polachek collab

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, caroline, chris.
