Ozzy Osbourne was left green with envy when his wife SHARON became the star of their reality TV show.

The Black Sabbath frontman, who was guided through his solo career by Sharon after being fired from the band in 1979, often feels overshadowed by her fame since she went on to judge UK talent show The X Factor and was given her own chat show.

But he does enjoy the healthy time apart they enjoy as a result of Sharon's career commitments.

He says, "To be honest, I was a little bit (jealous) at first. It's not jealousy so much; I think my ego was damaged a little, but now I don't care as long as she's having fun and doing what she wants to do.

"It gives me a chance to have a break from her saying, 'When are you going to finish the album? When are you going to do this?'"
