NEW YORK (AP) - If she had to do it over again, Sharon Osbourne says she wouldn't have invited MTV's cameras into her home.
The cancer-stricken matriarch of television's favorite dysfunctional family told ABC's Barbara Walters that she's calling it quits after an upcoming, 10-episode season is through.
"This is definitely the last year," Osbourne said in an interview that will be broadcast on "20/20" Wednesday. "We can't do it anymore."
MTV's second season of "The Osbournes" begins Nov. 26. The first set of episodes drew record ratings for the network this spring and made aging heavy-metal star Ozzy Osbourne and his family household names.
Sharon Osbourne, who is fighting colon cancer, said the show has "changed us all so much." Her teenage children now have lawyers and business managers, she said.
"Because it's a moment in time, when we were innocent to it all, we went in feet first and you can't recreate that," she said. "Yes, now, this series, people will see what the first series has done to our lives and it will take people to the next stage. But after that, it's over."
There was no immediate comment from MTV, which was airing a special, "Catching Up with the Osbournes," on Monday.
The family hasn't exactly shunned the spotlight. ABC said Monday that Ozzy, Sharon, Kelly and Jack Osbourne will be hosts of the American Music Awards on Jan. 13. Daughter Kelly has recorded her own CD that's due out soon.
Sharon said Ozzy has begun drinking again in response to her cancer.
"We agreed to do the show and so the cameras are here all the time," she said. "So it's a little bit invasive right now and we have no privacy. You know when you're sick, you want to be on your own? I can't throw up on my own and Ozzy can't get drunk on his own."
Two of the Osbourne children, Kelly and Jack, participate in the series. An older daughter, Aimee, did not. She told Walters that she worries about what will happen to her father if anything should happen to Sharon.
"I don't think he even wants to know what life will be like without her," Aimee Osbourne said. "And I don't think he would last more than a year without her."
