Kerry Katona: "I'm not on drugs"

Kerry Katona has claimed that she is sick of the rumours about her being on drugs.

She insists that recent erratic behaviour and an unusual appearance on GMTV last week are the result of her being bi-polar and not a drug habit.

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."
