The Sugababes are an English pop girl group based in London, consisting of members Heidi Range, Amelle Berrabah and Jade Ewen. The Sugababes were formed in 1998 with founding members Siobhán Donaghy, Mutya Buena and Keisha Buchanan. Their debut album, One Touch, was released in 2000 under London Records. Donaghy soon departed from the group, which was later dropped by London. With the introduction of Range, the Sugababes signed with Island Records and experienced a higher level of commercial success, releasing three multi-platinum albums. The band survived a second line-up change when Buena left and was subsequently replaced by Berrabah. After eleven years in the band, Buchanan was replaced by Ewen. The fourth line-up signed with RCA Records in 2011 after parting with Island. Donaghy, Buena and Buchanan formed a separate group the same year, Mutya Keisha Siobhan.
In 2006, British Hit Singles & Albums named the Sugababes as the most successful female act of the 21st century with six UK number one singles and eighteen UK top ten hits. Their number one singles include such songs as "Freak like Me", "Round Round", "Hole in the Head", "Push the Button", "Walk This Way" and "About You Now". They have also accumulated five UK top ten albums (four of which have gained at least platinum certification), including chart-toppers Taller in More Ways and Change. The Sugababes have been nominated for six Brit Awards, winning one for Best British Dance Act in 2003. They have been a long-term fixture in the British tabloids due to their several line-up changes and alleged group infighting. The group released their seventh studio album, Sweet 7, in March 2010 before announcing an indefinite hiatus in 2011. On 15 March 2013 the group confirmed that they would release new material near the end of the year.
