The SUGABABES look set to split after bandmember KEISHA BUCHANAN admitted she "doesn't know" what the future holds for the trio.

Her comments come after AMELLE BERRABAH walked out on a string of gigs amid allegations Keisha was ‘bullying' her - allegations the singer denies.

But now Keisha - who is the band's only remaining original member - has spoken of her fears over the band's future.

She said: "She (Berrabah) hasn't spoken to anyone. I'm not going to lie to you and say everything will be fine because I don't know. But as far as I'm concerned, we're the Sugababes; me, Heidi and Amelle.

"The reason why I'm panicking and the reason why I'm crying is because maybe Amelle wants to do things on her own for good."

Keisha and fellow member HEIDI RANGE were forced to perform as a duo when Amelle missed a series of concerts and band appearances last week.

British tabloid The Sun claimed the star had fled the band after constant fights with Keisha, alleging she was bullied over the success of her solo material with U.K. rapper Tinchy Stryder.

Buchanan was quick to deny the claims, insisting she was "crushed" by the report - and has also rubbished claims her bandmate's worried family had called cops over the disappearance - insisting she was the one who had phoned police because she was worried Berrabah was upset over a friend's recent car crash.

She adds, "We thought she was broken up about the accident and were really worried. We did two shows without her, genuinely thinking her friend's been in a really bad car accident.

"I said to our management can we please get the police around there because I'm really, really worried about her. That request didn't come from her family or Heidi, it came from me. The police went round and checked on her. They said she's fine and had been home all week."
