Any hopes Jade Ewen had of avoiding the wrath of Keisha have probably well and truly gone up in smoke since Heidi's latest outburst.

Since she's now officially the longest serving member of the band, it sounds like Heidi has got a bit big for her boots and has gone all alpha female.

Despite saying yesterday that she would in no way slag off Keisha because she has so much "respect" for her, Heidi has been mouthing off about how the Sugababes weren't that great before she graced them with her presence.

She told Radio One: "I don't want to sound like I'm being bigheaded but the Sugababes had one album which didn't sell and they were dropped.

"I joined eight years ago and we were signed together by Island Records. I've been there since our first number one Freak Like Me and been part of the history of the band ever since. Amelle has been in the group for over four years and she's been part of our biggest album as a group. I think it's unfair."

She then tried to soften the blow a bit by saying: "That's not disrespecting what previous members have brought to the group, but we were signed as Sugababes to Island Records and I'm still signed to Island Records as Sugababes."

Guess who'll be at the top of the list for the next ousting.

It's surely only a matter of time before the Sugababes bitching hits top gear. Here are a few of our favourite previous celebrity feuds...
