In 1998, the three band members formed the Sugababes. After the release of the debut album One Touch, Donaghy left the band and was replaced by Heidi Range. After the Sugababes released three more albums, Buena left the band in late 2005 and was replaced by Amelle Berrabah. In September 2009, the last founding member Buchanan also left the trio and was replaced by Jade Ewen.

The first hints of a reunion came in early 2012, when both Buchanan and Buena announced via their Twitter accounts that they were in the studio together with "two women". A short time later, singer-songwriter Emeli Sandé also confirmed to MTV News that she was working on material for the band. On July 20, 2012, the members announced the reunion via their Twitter accounts. The band's music has since been released by record label Polydor. Since the band Sugababes still existed at the time of the reunion, a combination of the singers' first names was chosen as the band name.
