Music's Bitchiest Feuds

As the world and his wife knows by now, Keisha Buchanan's MSN Xclusives performance was her last as part of Sugababes. In the old days, the band's PR machine might have been able to keep a lid on the true nature of her departure but, thanks to the mighty Twitter, it wasn't long before we all knew the split was far from amicable.

Tweeting shortly after the news broke, Keisha wrote, "Although it was not my choice to leave, it's time to enter a new chapter in my life. Sometimes a breakdown in communication and lack of trust can result in many different things".

Once it was established that she'd been pushed rather than had jumped, it was open season. Speaking to the Daily Mirror, Amelle said, "I was depressed. You shouldn't have to go to work treading on eggshells... Keisha didn't leave off her own back – me and Heidi couldn't carry on. Heidi completely supported me and knew what was going on within the band. But we all couldn't work together anymore. We weren't happy, me and Heidi, and it was a struggle to come into work. We didn't enjoy it.”

And to think, their last album before the split was joking titled Catfights and Spotlights.
