I think they have some nerve on them. Keisha and Mutya were more than happy to work with Heidi for years and years reigning in their successes and hit singles considering they didn't hit it big until Heidi joined. Again Keisha was more than happy to work with Amelle as they again reached the top spot. Siobhan walked off stage during a concert and never came back...speaks volumes about Keisha and Mutya and her relationship with them. Now suddenly they are best friends and taking on the new Sugababes because all three know they don't stand a chance at successful solo careers. Just cements my opinion that they are bitches. Keisha and Mutya especially. Sugababes should just be left a lone completely and fade away respectively both lineups! The fans deserve that much.
