Kerry Katona has accused her ex-husband, former Westlife star Brian McFadden of using his kids to boost his musical career. The ex-Atomic Kitten singer has criticised MCFadden for launching another bid for custody of the couple's children Molly, five, and Lilly-Sue, four - insisting the move is nothing more than a publicity stunt. She says, "It's a shame Brian is so desperate that he has to use me and the children for coverage. "The last time he did this the social services came round and gave me a clean bill of health. Brian isn't around. He hasn't been for years. If it helps resurrect his career that died long ago then I wish him all the luck in the world."
