His family confirmed his death, stating he was surrounded by love.
Osbourne's passing occurred weeks after his final performance with Black Sabbath at the 'Back to the Beginning' charity event in Birmingham.
The concert was significant as it was his first and final time performing with the original band members since 2005, and it benefited charities including Cure Parkinson's, a disease he was diagnosed with in 2019.
Hours before his death, Osbourne shared an Instagram post featuring a sign from the event that read 'Back to the Beginning. The Final Show.'
