Never has the expression "you're your own worst enemy" applied to anyone more accurately than Kerry Katona. The reality TV star has got us all worried again by giving a, frankly quite disturbing, interview about what is really going on with her and husband Mark Croft. The video, filmed by the MTV crew who make Kerry's reality shows, sees Ms Katona answering a number of questions over the phone, but it's her agitated manner and slurring of words that really disturbs us. Gabbling away in an irritated voice, Kerry denies there being any problems between her and Mark, and says she has "no idea" why people dislike her husband. She also denies ever hiring a financial adviser and says she has no plans to "downsize", despite her rumoured money troubles. Kerry hops from side to side during the five-minute chat, sucking sporadically on a cigarette and blinking ferociously. At one point she rests the phone on her chest and whispers to the camera, "I'm not telling them anything! I could get 40 grand for doing an OK! shoot with these questions." Her erratic behaviour is causing those close to her to worry, with one pal saying, "Kerry seems to be in this state all the time." It is now thought that her latest MTV show may not even be broadcast. A source from MTV explained, "We're desperately trying to put a show together – but her behaviour keeps changing the game."
