Sharon Osbourne says doing her family's famous MTV reality show was the "biggest mistake" of her life.
She and Ozzy "both worked to continue a lifestyle we had become accustomed to and we had to travel so my kids spent quite a time away from us and you can never get that time back.
"It was the biggest mistake I ever did, but would I have wanted to live a lesser life? You make the most of what you have.
"I don't know how, but Jack and Kelly came out just great," she said.
Sharon also admitted that she and Ozzy split up when he relapsed earlier this year, but they've since reconciled.
The TV hostess said she moved out because of his drinking and drug use, but now he's clean and sober thanks to a 12-step program.
"He stopped because he knows what he was going to lose, not just me but everything. He says we're like bread and butter. We fit together so perfectly."
