Charli XCX's scrapped third studio album, commonly given the title XCX World, is an unreleased studio album written and recorded from 2015 to 2017, with a version of the album being finalised in mid-2016. After being delayed multiple times, it was eventually shelved, and leaked in August 2017, ultimately causing its release to be cancelled. Charli XCX then started working on new projects, which eventually became her late 2017 mixtape titled Pop 2 and her 2019 self-titled third studio album. The album's photoshoot, shot by Bradley & Pablo, also leaked in August 2018. Charli XCX has stated that she's aware of the album's popularity between her fans; that she loves the songs that were meant for it, but the album will likely never be released.
Although never officially named, the album was christened XCX World by the artist's fans, who created multiple bootleg recreations of the album with different artworks, and an unconfirmed tracklist. Charli XCX has confirmed that her fans made all of these decisions, and in reality there was never a finished work. 
Despite the album's unfortunate fate, Charli XCX repurposed and officially released "No Angel" and "Girls Night Out" — previously teased and unreleased songs from the album —, as installments from a series of monthly singles in the summer of 2018. However, by the end of 2021, other leaked tracks that are very requested by fans, such as "Come to My Party", "Bounce", and "Taxi", remain unreleased.
Late 2014 - Early 2016: Production beginnings, SOPHIE and the Vroom Vroom (EP)
In December 2014, following the release of predecessor second studio album titled Sucker, Charli XCX revealed that she was already planning her then upcoming third studio album. She stated that it would be inspired by Japanese pop music and that it would sound like "another planet up in the clouds" and "intensely childlike". 
In January 2015, Charli XCX hinted that she had begun creating new material after being spotted with other singers, songwriters and music producers during Camp Skimret 2015 writing camps in countryside Sweden. About it, she said that "it was kind of just a hangout where we all make music and party for a week".
In July 2015, Charli XCX shared in an interview that she was working on her third studio album and described it as "the most pop thing, and the most electronic thing" that she had ever done.  It was also known that Scottish producer SOPHIE, along with BloodPop and Stargate, were confirmed to be involved in the album's production. Other pop producers such as MNDR, The Invisible Men and MNEK, were also confirmed to be part of the album's production. 
In October 2015, Charli XCX released the song "Vroom Vroom" on the Beats 1 Radio Show, then claiming it would be the first song released from her third studio album. The song was considered to be a preview of what she was working on in the studio. 
Charli XCX set up a new label called Vroom Vroom Recordings, and she would later release an extended-play titled Vroom Vroom under her own imprint record label on 26 February 2016.  Later that day, a song titled "Trophy", featured on the EP, received its first play on Zane Lowe's Beats 1 Show. A music video for "Vroom Vroom" was released on 22 April 2016 via Apple Music. All songs on the EP were produced by SOPHIE and meant to be included on Charli XCX's then upcoming third studio album.
Late 2016: PC Music, After the Afterparty and The Exchange
In July 2016, it was announced that British producer A. G. Cook, founder of record label PC Music, had signed on as Charli XCX's creative director.  The following month, Charli XCX said in an interview with The Fader that her album was finished and that it would be released in 2017.  She also revealed song titles for the album, including "Good Girls" and "Come to My Party",  the former being described as "playing around with gender expectations".  When describing the project, Charli XCX stated that the album would be split into two different sides, half being "straight-up pop", and the other half being "club orientated".
On 28 October 2016, the single "After the Afterparty" featuring American rapper Lil Yachty, was released as the intended lead single from the album. The music video was released two days later. The song charted at 29 on the UK Singles Charts and was certified silver by the British Phonographic Industry (BPI). Later that month, the album was confirmed for a May 2017 release.
On 10 November 2016, Charli XCX performed at Exchange, Los Angeles, along with SOPHIE, where they debuted numerous new songs written and recorded with the intention to be included on the album. "Roll With Me" (which would later be included on Number 1 Angel), "Bounce", "Taxi", "No Angel", among others, were all teased by Charli XCX herself during performances throughout late 2016 and early 2017.  She would also perform "After the Afterparty" — the album's then recently released lead single —, and the songs previously released on the Vroom Vroom EP.
Early 2017: Jimmy Kimmel Live! performance, Number 1 Angel and album delays
In November 2016, Charli XCX first teased the concept of releasing a mixtape before the album is released. In January 2017, she stated in an interview with Rolling Stone that she was already planning the release of a mixtape before the release of her third studio album. She described it by saying that "this is more like crying into the champagne than drinking it".
On 8 February 2017, Charli XCX performed "After the Afterparty" on Jimmy Kimmel Live!, along with previously teased and unreleased song from the album titled "Bounce", featuring Japanese hitmaker Kyary Pamyu Pamyu. She said in an interview later that month that her album was finished and set to be released in September 2017. 
On 10 March 2017, Charli XCX officially released her third mixtape titled Number 1 Angel, which included several songs written and recorded during the sessions for her third studio album, such as "Babygirl", featuring American-French singer-songwriter Uffie; and previously teased "Roll With Me", produced by SOPHIE. The mixtape was slated for a February 2017 release but was pushed back due to label conflicts. Charli XCX initially recorded the mixtape without her label's permission, stating that the situation, along with the album delay, had her feeling "frustrated and annoyed". At the time, Charli XCX described the album as a "party album" and stated that she "got caught up in it".
On March 17 2017, Charli XCX confirmed to Paris Hilton, via The Beat Juice interview, the existence of a new song for her upcoming album titled "Waterfall", which she described as being "very strip clubby and sexy, but also emotional as well".
Late 2017: Boys, leaks and cancelation
In May 2017, the album was delayed again with an expected release date for spring 2018. In an interview with The Fader, it was revealed that the album was completed in mid-2016. The album was allegedly edited a bit in early 2017, with more experimental songs being cut and more mainstream songs, such as "Blame It on Your Love", replacing them with the concept still being alive, yet changed. Charli XCX began recording songs written by other songwriters, such as "Our Boyfriend", "Issues", and "Boys"; the latter was released on 26 July 2017 as the second single from the album, with the music video release coinciding its release. The video was directed by Charli XCX, with additional direction from Sarah McColgan, and began production in April 2017.
On 20 August 2017, most of the album leaked on the internet after being scammed from the person who was mastering the album, which led to the album being officially cancelled. Charli XCX then decided to focus on making an entirely new third studio album, which eventually became the album Charli (2019), after releasing the mixtape Pop 2 in December 2017.
Early 2018 - Late 2019: No Angel, Girls Night Out, photoshoot and The Fader interview
In the summer of 2018, Charli XCX officially released previously teased and unreleased outtakes from the album "No Angel" and "Girls Night Out", as installments from a series of monthly singles. However, other leaked tracks that are very requested by fans, such as "Come to My Party", "Bounce", and "Taxi", remained unreleased. In August 2018, the album's photoshoot, shot by Bradley & Pablo, also leaked.
In September 2019, Charli XCX revealed in an interview with The Fader that she never officially gave the album a title, and that XCX World is just a name fans had given to it; stating that the album "was never really a fully formed thing". She had also confirmed that she had shot the album artwork — which also leaked in August 2018 and was confirmed to be shot by Bradley & Pablo —, and that she was about to shoot music videos before the leak happened. During the same interview, Charli XCX explained that the decision to scrap the album was "out of her hands", and that the material will never be released because "that time is really tainted" due to somebody hacking her, even though she loves the songs that were meant to be included on it.
Early 2020 - present: Cultural impact, Taxi, performances and steams
Fan-favourite unreleased from the album "Taxi", were performed many times during XCX's Charli Live Tour in early 2020. In March 2020, unreleased songs from the album, such as "Come to My Party" and "Taxi", were performed in a virtual concert. Other performances were made between the following months to promote her quarantine-inspired album How I'm Feeling Now (2020).
In January 2021, information around the promotional conception of the album leaked onto the internet, alluding the creation of an "XCX megabrand" and an "XCX universe", along with a strong rollout planned for the album's release; including promotional slots, online campaigns, and after parties with fans. It was also revealed that the album was planned to be simply titled XCX, and officially released as late as the end of May 2017. However, none of these ideas came to fruition. Later that month, the album cover was confirmed by Charli XCX herself through her Instagram account.
In February 2021, other songs meant to be included on the album began being shared online by fans. In October 2021, information about the album's sessions and stems from intended songs were also leaked.
During promotional interviews to her album Crash (2022), she was asked many times about a release of fan-favourite unreleased song from the album "Taxi"; she hinted that the song would "hopefully be out one day". On 25 March 2022, Charli XCX used her Twitter account to ask fans about a shared link to have access to the leaked tracks. The next day, songs meant to be included on the album back in 2016 were heard being played during the pre-shows and after-shows from her Crash The Live Tour.
