The Black Sabbath rocker can't believe their reality show, 'The Osbournes' - which ran for three years in the early 2000s - was so popular but by the end of it, he "ended up going f****** nuts".

He said: "I don’t understand what people saw in it. It wasn’t scripted. Not like ['Keeping Up With The] Kardashians'. I find it hard to believe that’s not scripted.

"But we just had a camera crew in our house 24/7, 365 days a year, and you end up going f****** nuts! You can’t run off. And after three years of filming it the kids were all on drugs, Sharon was battling cancer and so I said to the family, ‘Do we want to carry on?’ and they said, ‘No’, so we pulled it."

The 71-year-old star doesn't regret the show though as it gave him and his family - wife Sharon, daughter Kelly, 36, and son Jack, 35 - a "different level of fame" like Beatlemania.

He added: "I’m glad we did it because we reached a different level of fame. But it was like Beatlemania. It wasn’t fun. I remember going to a McDonald’s to use the bathroom and everyone started chasing me around the car park. I was freaked out."

Whilst he doesn't regret the show, Ozzy admits he has done "some pretty outrageous things" in his life and his biggest regret is cheating on his wife.

Speaking to GQ magazine, he shared: "I’ve done some pretty outrageous things in my life. I regret cheating on my wife. I don’t do it anymore. I got my reality check and I’m lucky she didn’t leave me. I’m not proud of that. I was pissed off with myself. But I broke her heart."
