Kelly: Leave Olsen alone

Recovering drug addict Kelly Osbourne is urging the press to leave troubled teen Mary-Kate Olsen alone, as she struggles to beat an eating disorder in rehabilitation.

The Osbourne's daughter, who is famous for poking fun at her famous peers, has deep empathy for the ailing Olsen twin after Osbourne checked into rehab earlier this year to kick her painkiller use.

She says: "It is such a horrible thing to go to kick something like that, and it's not like, 'Oh, you go to rehab and you're cured.' You have to deal with that for the rest of your life."

Osbourne, who checked out of rehab in May, praises Olsen for seeking counselling in the first place - because she knows how vital it can be for struggling young girls.

She adds: "I'm doing absolutely fabulous. I think it was one of the best things that ever happened to me. You can only ever learn from your mistakes."
