'Dancing with the Stars' contestant Kelly Osbourne has blamed her genes for her drug addiction.
Kelly's father, rockstar Ozzy Osbourne, has had a long struggle with drugs, which makes her believe her DNA was pre-programmed to make her an addict.
Contactmusic quoted Kelly as telling BBC Radio 5 Live: "I don't have any shadow of a doubt that addiction is a disease. It is in your genes.
"I consider myself lucky that I saw both sides of it. Drugs stop you from screaming on the outside, but you are still screaming on the inside.
"I was addicted by 16. Drugs stopped me from feeling a certain way. Some people experience euphoria but I never felt that. They numbed me and gave me confidence.
It was like a magic medicine."
The 24-year-old Kelly has been in rehab four times and is presently drug free.
