Siobhan quits Sugababes!: to be replaced by an ex-member of Atomic Kitten! (NB not Kerry) Say it ain’t so! My pop dream is shattered – it’s emo for me all the way now, sob! Seriously this is bad news as the Sugababes were individual and interesting at a time when British teenpop needs those qualities, and fond though I am of AK, the choice of an ex-Kitten will not do wonders for the Sugababes’ precious cred.
