In a December 3 tweet, Charli XCX posited the idea of a "pretty cool mixtape" featuring her alongside the likes of Carly Rae Jepsen, Cupcakke, Mykki Blanco, and many more guest artists. On Wednesday night she confirmed that the mixtape is both real, and coming out next week.
Speaking to host Annie Mac, Charli said of the song: "It's the first song from a very real mixtape that myself and A.G. have been working on for the past couple of months. It's called Pop 2. It's going to drop a week from now but I might release a couple of songs before the full thing. It's coming."
Pop 2 will be the second Charli XCX mixtape of 2017 following Number 1 Angel, which arrived in March.
