Sharon Osbourne

When you're a British celebrity, you've got to deal with the British tabloids -- and for Ozzy and Sharon Osbourne, that means periodically waving away rumors, like the ones suggesting the long-married rock power couple is teetering on the verge of divorce.

Over the last fifteen years or so, the lives of Sharon and Ozzy Osbournehave pretty much been open books for all to gawk at. Now Sharon is opening the book to show how DNA testing saved her life.

Nobody wages a public feud quite like an Osbourne, as NBC discovered recently when the clan’s matriarch Sharon, wife and manager of Black Sabbath singer Ozzy Osbourne, quit her post as a judge on ‘America’s Got Talent‘ while blasting the network for allegedly discriminating against her son Jack after he was diagnosed with multiple sclerosis.

After Tony Iommi announced he was battling cancer and Bill Ward became enmeshed in contract disputes, Black Sabbath put the kibosh on their reunion tour plans — but Ozzy Osbourne’s wife and manager Sharon says that Sabbath will in fact perform a single show in the U.S. later this year.

On yesterday’s episode of ‘The Talk,’ Sharon Osbourne excitedly announced that she’s about to be a grandmother for the first time. Osbourne’s son Jack is expecting a child with fiance Lisa Stelly in April.
