Ozzy Osbourne is nervous about a return to reality TV.
The 74-year-old Black Sabbath frontman and his family have signed a deal with the BBC for a series documenting their "new life back in the UK" but Ozzy is worried about it after their MTV series sent the family "crazy".
The Osbournes' reality show, the first of its kind, aired from 2002 to 2005 on MTV and featured the domestic life of Ozzy , his wife Sharon Osbourne, 70, and their kids Kelly, 38, and Jack Osbourne, 37, while their daughter Aimee Osbourne, 39, didn't wish to take part and Ozzy admitted he is wary about a new show.
Speaking on his SiriusXM channel, Ozzy said: "I don't know how the Kardashians have done it for so long. It sent us crazy at the end.
"I am not sorry I did it, but after three or four years I said, 'Do you know what, we’re going to lose somebody because it is getting too crazy'.
"There is rock and roll fame, which is pretty intense, but that Osbourne level was just unbelievable. The kids paid for it. They all ended up doing drugs. Jack got clean and sober on that show, Kelly messed up on that show, I was messed up and Sharon got cancer."
However, Ozzy insisted he will go along with the new show because Sharon insisted.
He said: "My wife sort of dropped something on me that the BBC are doing The Osbournes returning to England. I said, 'We are not having all that again'. But she said it is only for a bit.
"It gave Sharon a new career. She has become the television person in our family."
