Amelle Berrabah has reportedly quit the Sugababes.
The 25-year-old singer is believed to have left the pop trio, which also includes Keisha Buchanan and Heidi Range, and will be replaced by UK Eurovision entrant Jade Ewen.
However, representatives for the band and Ewen are yet to confirm any line-up changes.
It follows reports Berrabah walked out on the group following a huge bust up with Buchanan earlier this month.
No one could contact the brunette beauty - whose recent collaboration with rapper Tinchy Stryder, Never Leave You topped the UK singles chart - for days, leading her family to mistakenly fear she had been kidnapped.
A friend says she is deeply unhappy at the moment.
"(She) is scared of Keisha. She still loves the band and the last thing she wants to do is quit. But the problem needs to be addressed because she feels she is being bullied.
"Keisha will criticise her throughout the day and it has been going on for months."
The Sugababes have a history of bust-ups within the band and Berrabah is the fifth member of the trio to quit.
