Ozzy Osbourne revealed that he was diagnosed with Parkinson’s disease.

In a new exclusive interview with “Good Morning America,” the Prince of Darkness shared the tough news with Robin Roberts.

“It’s been terribly challenging for us all,” Osbourne admitted. “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.”

The rocker received his diagnosis in February of last year. Although there is no cure for Parkinson’s, his wife clarified his diagnosis.
