The Black Sabbath frontman was diagnosed with Parkinson's Disease in 2003 but has had to endure several more health problems since, including a potentially deadly staph infection in 2018, pneumonia, and debilitating mobility injuries suffered during a fall inside his Los Angeles home in 2019, which resulted in multiple back and neck surgeries.
Sharon just revealed that Ozzy has "one more operation" before he can return home.
Appearing on Piers Morgan's new TalkTV show Uncensored, the former The Talk star revealed that her husband of nearly 40 years is "doing okay".
