Ozzy Osbourne has revealed that he's been diagnosed with Parkinson's disease.

Speaking on US TV breakfast show Good Morning America, he said that he has a "mild form" of the disease and received the diagnosis after suffering a fall in February of last year.

Wife Sharon joined him on the show and said: "It's not a death sentence but it affects certain nerves in your body. You have a good day, a good day, then a really bad day."

Ozzy, 71, revealed that he was taking medication to help deal with the onset of Parkinson's as well as for the nerve pain that he's suffered following the fall.

"It's been terribly challenging for us all," he said. "I did my last show [on] New Year's Eve [of 2018]. Then I had a bad fall. I had to have surgery on my neck, which screwed all my nerves."

Speaking about his fans, he said: "They're my air, you know. I feel better. I've owned up to the fact that I have... a case of Parkinson's. And I just hope they hang on and they're there for me because I need them."

He added that his health was improving however, telling Good Morning America that he is "a lot better now than [he] was last February. I was in a shocking state."

Ozzy is soon due to head back out for a US tour starting in Atlanta, Georgia, on 27 May. He will follow that line of shows with a series of rescheduled UK dates which will begin in Newcastle in October.
