Ozzy Osbourne reveals HIV scare

Ozzy Osbourne has revealed that he was once diagnosed as being HIV positive.

The singer told Glamour magazine: "I went to the doctor and had an AIDS test and he told me it was positive. That was one of the worst days of my life."

However, a second test came back negative. Doctors blamed the false first result on Osbourne's weakened immune system.

"When I used to f**king get loaded, I would get myself into all kinds of situations," the Black Sabbath singer said.

"It turned out that because I was drinking and using drugs so much, my immune system had dropped so that it was a borderline result. When I went back to be tested again it was negative."
