Apparently the Sugababes had a blow up, or at least with Heidi Range and Mutya Buena during an interview at Party in the Park.

“While being interviewed, someone asked them about all the in-fighting,” a source revealed.

“Heidi and Mutya said ‘Fu** this’, started aruging with each other and stormed off later, leaving Keisha Buchanan alone to continue the interview.”

Asked whether they’re going to split up, Keisha said “No, we’ve too much respect for our fans.”
