Original Sugababes star Siobhan Donaghy is adamant the band's former members will never share a stage with the current line-up of the girl band, dismissing fans' hopes of a supergroup tour. Donaghy has reunited with her former bandmates Mutya Buena and Keisha Buchanan to form a new girl group called Mutya Keisha Siobhan. All three singers were replaced when they left the line-up and the current band features Heidi Range, Amelle Berrabah and Jade Ewen, who recently voiced her hope that the two bands could be combined to form a Sugababes supergroup, telling Digitalspy.co.uk, "That would be awesome, it would sell out... I'm definitely up for it." However, Donaghy is adamant it will never happen, telling Britain's Metro newspaper, "People have to remember, especially for me, I have only ever worked with Mutya and Keisha, that's my focus and that's what I enjoy. There will be no tour together." She adds of the later incarnation of the Sugababes, "If I'm completely honest, I wasn't really a fan."
