Sugababes' latest line up has managed to last just 12 days before having their first fall out, it's been reported.

New member Jade Ewen and Heidi Range are understood to have been left upset on Friday when Amelle Berrabah's phone kept ringing during a photo shoot.

According to The Sun newspaper, the session was delayed for two hours while the girl group's management tried to calm the situation.

A source said: "The others were kept waiting and got increasingly wound up.”

Ewen was unveiled as the latest Sugababe last month following the departure of original member Keisha Buchanan.

The new trio teamed up for the first time just days later to shoot the provocative video for their new single.

They are also re-recording forthcoming album Sweet 7 with Ewen's vocals.
