Background and recording In 2017, Charli XCX was preparing to release her third studio album. However, a hacker was able to steal several demo tracks from her Google Drive and leaked them online. Fans gave the collection of leaks the unofficial title XCX World, though a title and track list was never finalised for the album. After the leaks, Charli XCX decided to scrap the entire project and decided to remake a new album. After a series of monthly single drops in the summer of 2018, Charli XCX released the lead single of the album, "1999" in October 2018. Charli XCX and executive producer A. G. Cook continued recording the album in November 2018 at Flume's studio in Los Angeles, California. The project was initially intended to be the third release in a trilogy of mixtapes, following the release of Number 1 Angel and Pop 2. The title was to include the number "3", continuing the numbering motif, but the plan was never finalised. After two weeks of recording, Charli XCX decided that the work would instead be her third studio album. Recording continued in Eagle Rock from January to March 2019, where the majority of the album's songwriting and production took place. The song "White Mercedes" was recorded in Andrew Watt's home. Initially trying to keep the "3" in the title, a working title for the album was Best Friends before Cook suggested the title Charli. Release and promotion On 13 June 2019, Charli XCX announced Charli, along with its cover art, release date, and track list that featured 15 tracks and 14 collaborations. Charli XCX debuted "Gone" with Christine and the Queens at Primavera Sound in Barcelona on 30 May and "2099"
