Background: The Sugababes are a British girl group formed in 1998 by Siobhan Donaghy, Mutya Buena and Keisha Buchanan. Their debut album, One Touch, was released in the UK through London Records on 27 November 2000. The album achieved moderate success, peaking at number 26 in April 2001 and eventually being certified Gold. In 2001, Donaghy departed the group amid rumours of a rift with Buchanan and the group were dropped by their record label.
Context: Having already started work on a second album with new member Range, the trio looked for a new record label, eventually signing to Island Records. Their first single on the new label, "Freak like Me" scored the group their first UK number 1 single. Follow-up single "Round Round" also debuted on top of the UK Singles Chart and peaked at number 2 in Ireland, the Netherlands and New Zealand. Both singles were certified silver by the BPI. On the back of the success of the singles, the group's second album, Angels with Dirty Faces, debuted at number 2 on the UK Albums Chart and was later certified triple platinum, selling almost a million copies in the UK alone. It is to date their highest-selling album. In the UK, the third single from the album, a ballad titled "Stronger", gained the girls their third consecutive top ten hit in their native country. The track was released as a double-A side with "Angels with Dirty Faces" in the UK, the latter song chosen as the theme tune to The Powerpuff Girls Movie. A fourth single, the Sting-sampling "Shape", made the top ten in the Netherlands and Ireland in early 2003.  The group's third album, Three, was released in late 2003 and reached number 3 on the UK Albums Chart, earning the group a BRIT Award nomination for Best Album. Certified double platinum, it has sold 855,000 copies to date. The album was preceded by lead single "Hole in the Head", which became the group's third UK number 1 single. It also reached number 2 in Ireland, the Netherlands and Norway, and became the Sugababes' first (and to date only) single to chart in the United States, reaching number 96 on the Billboard Hot 100. Follow-up single "Too Lost in You" appeared on the soundtrack to the film Love Actually and went top ten in Germany, the Netherlands, Norway and the UK. The album's third single, "In the Middle", was released in 2004 and garnered the group another BRIT Award nomination for Best Single; like its successor, the ballad "Caught in a Moment", it went to number 8 on the UK Singles Chart. In 2004, the trio sang on the Band Aid 20 remake of "Do They Know It's Christmas?", which went to number 1 in the UK in December.  Around this time, the group's perceived "moodiness", alleged backstage catfights, and press junket tantrums were tabloid fodder in Britain. They were surrounded by continuous rumours of in-fighting within the group and constant split reports. Rumours suggested that Buchanan and Buena had bullied Range, although Range herself repeatedly denied such allegations; Buena later admitted that she "just didn't talk to her" when she first joined. Buchanan claimed there was only one serious fallout between herself and Range during a 2004 gig in Dublin, regarding Britney Spears' "Toxic".
