British pop star George Michael has blasted his cannabis addiction as the "biggest regret" of his life.

The AMAZING hitmaker, who got hooked on the substance while mourning the death of his lover, AIDS victim ANSELMO FELEPPA, admits that although he successfully quit cigarettes, he will probably never be able to give up cannabis.

He says, "I don't smoke cigarettes anymore, thank God. I'm still smoking weed though, but I'm trying to give that up.

"I only started smoking at 30 - that was stupid. I started after Anselmo died and it was the worst thing I ever did.

"It was my biggest regret in life."
