Ozzy Osbourne was told he might not survive Black Sabbath's reunion gig

During an appearance on Piers Morgan Uncensored, Sharon explained: "He'd been so ill this year - terribly, terribly ill.

"And when we came to England and we were meeting with new doctors here, a new medical team for him, the main doctor said to him: 'If you do this show, that's it. You're not going to get through it'.

"But we just sat there, and he said, 'I'm doing it. I want to do it, and I'm doing it'. He knew his body was failing him. He was in so much pain, so much pain.

"And I mean, you know, he had pneumonia three times this year. He'd had sepsis.

"That's what really, really destroyed him. He was on these shots of antibiotics. It used to take 20 minutes for the shot to go in, and he had that twice a day, and it kills everything in you, the good, the bad, everything. So much antibiotics, and he just couldn't get over that. He just couldn't."

Sharon insisted Ozzy was determined to go ahead with the gig because he knew he wasn't going to live much longer.

She said: "He just wanted it so bad to say thank you to everyone. And I think he honestly did know that, he, he was done. That was his time."

The TV star went on to insist performing one last time made Ozzy incredibly happy and his final two weeks were like "sunshine".

She said: "He was so happy afterwards. He kept looking at the papers, and he goes to me: 'I never knew so many people liked me', but that was the way he was.

"I mean, he knew he was famous, but not the amount that people loved him. It's a whole different thing, and he was just so happy, so so happy.

"And for two weeks he was, you know, really, like every day was sunshine for him. Really, really happy, yeah, so happy - happier than we'd seen him in seven years."
