Reuters reports that Sharon Osbourne, matriarch of MTV's first family, "The Osbournes," says the constant presence of cameras in their home is getting to her and she wants to call it quits at the end of the upcoming season. In an interview for a special edition of the ABC News program "20/20," to air on Wednesday, the wife and manager of British rocker Ozzy Osbourne also said she regrets putting her family on television in the first place.

"This is definitely the last year," Sharon Osbourne, 50, told Barbara Walters in excerpts of the interview released by Walt Disney Co.'s ABC network. "We can't do it anymore. ... Another 10 shows and I'm out." She said the strain of living in a fish bowl has become especially hard as her family copes with her battle against colon cancer, a crisis she said is driving her husband to drink.

"Ozzy's been hitting the bottle again," she said. "And, we agreed to do the show, and so the cameras are here all the time. ... we have no privacy. You know when you're sick, you want to be on your own? And I can't throw up on my own, and Ozzy can't get drunk on his own."

An MTV spokeswoman said there was no immediate comment from the Viacom Inc.-owned cable music network.
