Ozzy Osbourne is having a major surgery Monday that is “going to determine the rest of his life,” according to his wife Sharon. 

She didn’t provide more details about the surgery, but multiple reports have said the 73-year-old “Prince of Darkness” has been having severe neck pain for a long time.

The singer posted to social media just hours before his “life-altering” surgery today sharing his 2010 song “I Love You All” and zeroing in on the lyrics, “For all these years you’ve stood by me / God bless, I love you all.”

A source close to the family also said Osbourne will need a “lengthy amount of convalescence” due to his age and the intensive nature of the surgery, which will remove and realign pins in his neck and back.
