Following last night's (11 May) BRIT Awards, Charli XCX praised Rina Sawayama's vintage Balmain couture dress by tweeting that she "woke up at 5:30am thinking" about it, and shortly after Charli XCX followed it up with another tweet, writing, "and then we texted about making a song".

The two are yet to collaborate on a song together, but there is a possibility both Charli XCX and Sawayama may feature on BloodPop's Chromatica remix album, as BloodPop previously said he's "working on" a Charli XCX remix of "911".

Last night (11 May) at the BRITs Sawayama confirmed that she's "done my bit" on the upcoming Chromatica remix album, and while she didn't provide any information about what song she'll be on, Sawayama did say, "It's a song that's hard to sing with my new braces."

Charli XCX finally united with A. G. Cook last week on "Xcxoplex", a rework of last year's Apple track "Xxoplex".
