The veteran rocker has recently criticized Pete Doherty's life style.
Ozzy, who has faced some drugs problems in the past as well, thinks the Babyshambles frontman doesn't seem to understand the repercussions of his wild actions. Doherty, who has been ditched by his girlfriend, supermodel Kate Moss, is wasting his life on drugs.
"I get angry seeing this little f***ing junkie, Pete Doherty", Osbourne said.

"Doesn't he realize that if he carries on he's gonna die?", he added.

Talking about his wilder days, Ozzie also revealed he swore never to sleep with a groupie again. Apparently, nowadays, his wife, Sharon, gets more love offers than he does.

"When the thought of sex finally filtered through the haze of booze, all the good-looking groupies had gone home. You'd wake up and there'd be this thing lying there looking like something Picasso had painted on a bad day", Osbourne confessed.

"I still get offers now but I'm not interested. Sharon gets propositioned more than I do", he added.

Earlier this year, Ozzy, who is past his boozing days, has met the Queen at an event, chatted with her afterwards and said she was "really warm and friendly".

"I was standing next to that muppet thingy, Kermit the Frog, with Rod Stewart punching it in the head," he said.
