Sugababes: The original line up of the Sugababes (Mutya, Keisha and Siobhan) were notoriously bitchy and would constantly row behind the scenes. The majority of the tension reportedly came from Mutya and Keisha''s close relationship which often left to Siobhan feeling isolated. The two girls also created a special language they would use to bitch about Siobhan, which can''t have helped relations much either. The three girls are back together now, with all fingers crossed they have put the past behind them and can move forward minus the fights.
