According to onlookers, Heidi Range and Keisha Buchanan are not that interested in exchanging words. The British all girl band recently performed a gig at the Royal Albert Hall. But, according to eye witnesses the two stunning members of the band didn't swap a single word. "I don't think Heidi and Keisha said a word to each other. They stayed in different rooms," The Sun quoted an onlooker, as saying. The Sugababes have a history of bust-ups with ex-members Siobhan Donaghy and Mutya Buena.
