Keisha denies Sugababes rift

Singer blasts rumours she is bullying Amelle

Original Sugababe Keisha Buchanan has blasted rumours she is bullying bandmate Amelle Berrabah by posting a succession of status updates on her Twitter page.

Responding to today's tabloid reports that Amelle had gone 'missing' from the band for four days following a bust-up with Keisha, the 24-year-old wrote:

'I may come across as a hard nut sometimes, but I'm actually really sensitive and it destroys me to think that people today are going to read that and believe it. I feel like noone EVER bothers to look deep in 2 the Sugababes story.'

She continued: "They see me as the longest standing memberand assume that I'm the bitch who causes people to walk, and its totally untrue and unfair...

'All I've ever done is work my ass off, trying to keep the dream alive, because I love the fans and my job. I don't give a s**t about being famous, we're all on the same level.

'I've always put this band b4 me & never thought that I was bigger than it... its a great team effort.'

Also responding to long-gestating rumours that she bullied founding member Siobhan Donaghy, she wrote:

'It's fair 2 say in the 1st line up that there were arguments, certain parents were involved then callin shots which caused a lot of s**t.'

Meanwhile, Amelle made her presence known by posting a message on her own Twitter page.

'MISSING!!!?', she wrote. 'Is this some sort of joke!!!!! I'm not bloody missing!!!!!'
