Singer Kelly Osbourne was so high on drugs throughout the filming of reality TV hit THE OSBOURNES she was "like a zombie".

The PAPA DON'T PREACH star - whose father Ozzy and brother JACK have also had well-publicised battles with narcotics - was using prescription heroin as she made the show.

She says, "I'd been doing drugs since I was 13.

"I think drug addiction is a genetic disease - my dad's had it, so has my brother.

"No one would look down on us if we had cancer."
