Ozzy - "Who the f*** is Colin Farrell?"

Ozzy Osbourne doesn't like the idea of Colin Farrell playing him in a movie of his life - because he hasn't got a clue who the actor is. .

When asked what he thought of rumours suggesting the Irish hell-raiser would play him, the rocker said: "Who the f*** is Colin Farrell?" .

Ozzy and wife Sharon have previously recommended 'Pirates of the Caribbean' star Johnny Depp for the role. Meanwhile, the former Black Sabbath frontman has revealed the best and worst rehab clinics in America. .

Ozzy, who has been in and out of rehab all his life, revealed to Playboy magazine: "Betty Ford is a good one. And a place called Promises, in Malibu, which is like a f***ing Hollywood camp resort for wealthy f***ing lunatics." .

However, the star - whose son, Jack, and daughter, Kelly, have also spent time in rehab - wasn't so impressed with the Hazelden centre in Minnesota.

He explained: "It's a really hard one. They do not f*** around. I checked out because it scared me. .

"They use a thing called tough love, where they're like 'You f***ing piece of s***!' I was like, 'I felt like a piece of s*** before. That's why I am paying you all this money. You don't need to tell me every day.'"
