In the interview, the musician explained that he was diagnosed with a form of Parkinson's disease last February after suffering a fall and needing neck surgery.

Ozzy, now 71, was visibly shaken when he revealed his diagnosis and talked about what the last 12 months have been like for him and his family.

"It's been terribly challenging for us all," Osbourne told GMA. "I did my last show New Year's Eve at The Forum. Then I had a bad fall. I had to have surgery on my neck, which screwed all my nerves."

His wife Shannon Osbourne, 67, elaborated on the rocker's illness: "It's PRKN 2," said Sharon. "There's so many different types of Parkinson's; it's not a death sentence by any stretch of the imagination, but it does affect certain nerves in your body."

"And it's...it's like you have a good day, a good day, and then a really bad day." Now we know why Ozzy postponed his world tour and has been living a rather secluded life for the last year.

He also explained that he just had to come clean after the last 12 months: "I'm no good with secrets," Osbourne said. "I cannot walk around with it anymore 'cause it's like I'm running out of excuses, you know?"

We certainly wish the heavy metal legend all the best for the future!
