Sugababe Keisha Buchanan is trying to make peace with her former bandmate Mutya Buena after colleagues Heidi Range and Amelle Berrabah quarreled with the British singer. Berrabah took over from original group member Buena when she left to pursue a solo career in 2005, but the two fell out when Buena accused her replacement of copying her look last week (ends27Apr07). Buchanan, who helped set up the Sugababes, now wants to resolve the issues and get back on speaking terms with her former friend. She says, "There is no need for all this. I think sometimes people regret the mistakes they have made and like to put blame on whoever they want. Why can't we all be happy?"
