The TV star has three kids with her heavy metal legend husband Ozzy Osbourne; Aimee, 34, Kelly, 33, and Jack, 32.

The family became household names when they starred in MTV fly-on-the-wall reality series 'The Osbournes' but Aimee chose not to be part of the programme - which began in 2002 and documented every aspect of their home life, and so moved out and Sharon now wishes she'd chosen her daughter's wish for privacy over fame.

Speaking on TV show 'The Talk', she said: "My eldest girl, Aimee, left home at 16. She couldn't live in our house because we were filming and it drove her insane. She felt too that she didn't want to grow up on camera. She hated the idea. It was appalling to her. And so she left at 16 and I regret every day that she did. She was happy but it broke my heart when she moved out."

Sharon, 65, and Ozzy, 69, are now grandparents to Jack's three daughters, six-year-old Pearl, Andy, two, and four-month-old Pearl - his kids with estranged wife Lisa Stelly.

And 'The X Factor' judge admits she wants to work less so she can be a big part of her grandchildren's lives.

She previously said: "Pearl did her first nativity play at school and I was actually in England, and I'm like, this is insane, because it's history repeating itself. I missed all my kids' things, Ozzy did too, and now we're gonna miss everything with the grandkids. You look back - and we've had an amazing life together, unbelievably gifted - but you give up something when you have this life. You give up friends. You give up memories of going to people's weddings, birthdays, school events."
