We're learning more about the sudden death of Ozzy Osbourne. The heavy metal icon passed away at 76 years old on Tuesday after a years-long battle with Parkinson's disease. The news came as a shock to celebrities and fans. Ozzy's death was also "unexpected" to his own family, though they were by his side during his final days at his Buckinghamshire mansion. They all reportedly hoped the singer "would be able to carry on for a bit longer" after his final performance with Black Sabbath earlier this month. Sadly, it didn't happen.
