Aimee Osbourne has yet to appear on The Osbournes -- and won't be on the show any time soon, says family matriarch Sharon Osbourne.

"Everybody had a decision to make, and [Aimee's] decision was that she keep her life private and she didn't want to be in the spotlight at this time," Sharon Osbourne said on Monday's Larry King Live.

"She is pursuing a singing career . . . but at this time she didn't want to be part of our show. So I can only respect her for that."

Yes, host Larry King said, but what happens when Aimee -- the oldest child of Ozzy and Sharon -- comes over to the family's Beverly Hills mansion?

"The cameras don't shoot," Sharon said. "It is awkward, but you know, it's our daughter so that's it."

Sharon also said she's not sure the show will continue beyond its third season, which kicks off in June on MTV.

"Well, we have another season in the can . . . which I think airs in June," she said.

"I honestly don't know if there will be another season. Let's say in the next year I can't foresee it, but maybe after that. Right now I don't know."

"Next year can you foresee doing the show again?" King asked.

"No," Sharon replied.

She also took some shots at Bill Cosby, who last year lambasted the Osbournes for their on-camera behavior and liberal use of profanity and called them a "sad" family.

"Well, I call him a hypocrite," Sharon said of Cosby. "Because he pretends to be squeaky clean and he's not.

"And his reputation precedes him," she said. "I mean, I don't know . . . but people in TV and film have told me otherwise.

"I mean, I don't know, I don't know him," she said. "I must say, however, that when I got ill . . . he sent me a very nice letter, so, you know, I don't want to knock him too much."

Sharon, who was diagnosed with colon cancer last June, has undergone chemotherapy treatments and told King she's "doing great. I'm really, really good."

She's scheduled to host a talk show next fall distributed by Telepictures, an arm of AOL Time Warner.
