Former Atomic Kitten singer Kerry Katona has kicked her husband-of-six-months out of their home after allegations he cheated on her. The British reality TV star and magazine columnist, 26, is disgusted by reports Mark Croft had sex with a former flame just days after proposing to her, as well as romping with another mystery woman. Her publicist Max Clifford confirms, "She is absolutely devastated. She's been on the phone sobbing. I really feel for her. "Mark denied the allegations but Kerry's very upset. This must be the worst time of her life." Katona was previously married to Irish pop star Brian MCFadden, who she has two daughters with.
