Range: 'Being a Sugababe was unbearable'

Heidi Range has admitted that she found it "unbearable" to be part of Sugababes after problems developed in the group's third lineup.

The chart-topping band underwent another revamp last year as founding member Keisha Buchanan was ousted and replaced by Eurovision star Jade Ewen.

Discussing the group's reinvention, Range told the Daily Mail: "Now we're all on an equal footing. Before that, we never knew from one day to the next what mood or hurtful comments to expect. The last year was unbearable because it was so stressful."

Range's bandmate Amelle Berrabah added that the pair had agreed to work things out with Buchanan and give her "one last chance" when they were about to film the video for their single 'About A Girl'.

However, Heidi said: "We realised that nothing was going to change. We told our managers that we couldn't face another day. [But] our managers told us, 'We want you both to stay'. The next thing, Keisha was gone, and we've not heard from her since."

Buchanan has repeatedly denied suggestions that she bullied her bandmates. Writing on Twitter last year, she warned: "To those who accuse others of being a bully for self gain, think first! It's a very serious allegation."
