Sweet 7

Sweet 7 is the seventh studio album by British girl group Sugababes, released on 5 March 2010 by Roc Nation and Island Records. Production for the album began in April 2009. Sweet 7 is the only Sugababes album to feature Eurovision Song Contest 2009 entrant Jade Ewen, who joined the group following the controversial departure of Keisha Buchanan in September 2009. As a result of the group line-up change, Sweet 7 was re-recorded to feature the vocals of new member Ewen and for the removal of Buchanan's vocals, making this the only Sugababes album that features none of the original members.

Production on the album began with Buchanan's involvement, who was featured on the lead single "Get Sexy", which peaked at number two in the UK. Following her departure, "About a Girl" and "Wear My Kiss" peaked at number eight and seven, respectively. The album was written and produced mostly musicians attached to Jay-Z's entertainment company Roc Nation; the involvement of Roc Nation's in-house producers gave the album a strong electro and dance-pop sound, derived from music and producers popular at the time, including: Fernando Garibay, Stargate and The Smeezingtons. Despite the high-profile input, Sweet 7 was negatively received by critics, who criticised the lack of an identifiable sound and soul from the project, as well as the group's loss of identity due to Buchanan's departure; many considered it a major step down in quality from their previous work.

Sweet 7 peaked at number 14 in the UK and number 35 in Ireland, becoming the group's second-lowest charting album to date in those countries. Promotion for the album ended after the release of the third single "Wear My Kiss". It was widely reported that the album underperformed; Sugababes would go on to be dropped by Roc Nation and end up leaving Island Records for a new three-album deal with Sony Music via a joint venture between RCA Records and Crown MD. Although this line up would go on to release another song "Freedom", retrospective coverage about this period in the band's history noted that the underperformance of Sweet 7 ultimately led to the permanent hiatus of Berrabah, Ewen and Range's version of the group. This hiatus would trigger the original line-up (Buchanan, Mutya Buena and Siobhan Donaghy) reforming in 2012 and then later reclaiming the Sugababes name for themselves in 2019.
