Ozzy Osbourne has said that he was wrongly diagnosed as HIV positive.
"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," the Mirror quoted him as saying.
However, fortunately, the former Black Sabbbath's vocalist's second report came negative.
The doctors who treated him had apparently blamed the error on the singer's immune system, which had become weak due to years of booze and drugs.
He said: "When I used to get loaded I would get myself into all kinds of situations. 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."
