Ozzy Osbourne

The heavy metal icon revealed in 2020 that he had been diagnosed with Parkinson's following a fall the previous year.

The Black Sabbath rocker – who died at the age of 76 in July 2025, just weeks after his final performance - told Good Morning America: "I'm no good with secrets. I cannot walk around with it any more 'cause it's like I'm running out of excuses, you know?"
