Dancing With The Stars contestant Kelly Osbourne is looking good these days – a sharp contrast to her wild teenage years which saw her bloated and battling drug addiction.

Shockingly, the star first tried Vicodin at 13 after being prescribed it after her tonsils were removed, Kelly reveals.

But when she started going to night clubs, aged 16, her habit started to take hold after she was offered pills by a friend.
