Kerry Katona: "I am NOT on drugs"

Kerry Katona has rebuffed rumors of a possible drug addiction, as the 'I'm a Celebrity Get Me Out of Here' star storms live on GMTV.

She insists that her recent erratic behavior is due to her being bi-polar and nothing to do with any kind of drug addiction.

More quotes her as saying: "It's the bi-polar. I'm often up and down. I think that's why some people think I'm on coke.

"One minute you're 'Grrrrrr!' then the next you're down."

She added: "I find it sick that people think I'd take drugs while pregnant."
