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, Amelle and Jade are yet to confirm any line-up changes.
Amelle’s decision follows reports she walked out on the group following a huge bust up with Keisha 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 said: "She is deeply unhappy at the moment and 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. It has got worse since Amelle had the Tinchy Stryder single and featured big-time in the 'Get Sexy' video. Keisha is very dominating, while Amelle is quite placid."
The Sugababes - who are preparing to release their new album 'Sweet 7', which contains the hit single 'Get Sexy' - have a history of bust-ups within the band and Amelle is the fifth member of the trio to quit.
Heidi replaced original member Siobhan Donaghy in 2001, while Amelle was brought in after founding member Mutya Buena walked out on the girl group in 2005.
