The group were formed in 1998 by original members Siobhan Donaghy, Mutya Buena and Keisha Buchanan. After some initial success, Donaghy departed and the introduction of Heidi Range in 2001 was met with the commercial breakthrough of the group's first number-one single "Freak Like Me" and parent album Angels with Dirty Faces in 2002. The group survived a second line-up change in 2005, when Mutya Buena left and was replaced by Amelle Berrabah. In September 2009, it was announced that after eleven years in the Sugababes, Keisha Buchanan was no longer a part of the group and had been replaced by Jade Ewen.
Sugababes have released twenty five singles, six of which have reached number-one in the UK and twenty-two have reached the top 20 in the UK, With seventeen of their twenty five single releases achieving top ten chart success in the UK, Brit Award winners, the trio have been named the UK's most successful female act of the 21st century.
