The 65-year-old Black Sabbath star has credited his wife for helping him turn his life around after battles with drug and alcohol addiction, reported Contactmusic.
"Not here, that's for sure. I probably should have died years ago but she just wouldn't have it," Ozzy said.
The rocker is currently enjoying baked vegetables for his daily meals.
"I'm on this baked vegetable diet right now. I've only been doing it for a week or two, so it's not really a life-changing thing. I don't have meat on a Friday, and pizza on a Wednesday, and all this," he said.
