Kelly Osbourne's Dark Past

Former reality show wild-child turned singer Kelly Osbourne is opening up about her past as a drug and alcohol addict--and the details aren't pretty.

Osbourne, who was a drug addict at just 13 years old, admits that during her childhood she was at one point was taking up to 100 pills a day.

After three separate stints in rehab, Osbourne is now clean (cough cough). But she admits it wasn't easy, "All the voices in my head were telling me I was worthless."

Now I'm no doctor, but wouldn't she have died if she actually took 100 pills at the age of 13??
