Ozzy Osbourne can't stop worrying.

The Black Sabbath rocker - who has three children with wife Sharon Osbourne and three from his previous marriage - is constantly searching for something to be concerned about and feels uneasy if life is running smoothly.

Kelly Osbourne hid her girly side to please her rock star father.

The 'Dancing with the Stars' contestant - daughter of former Black Sabbath singer Ozzy Osbourne - claims appearing on the talent show has brought out a different side to her.

Kelly Osbourne has blamed her DNA for her addiction. The presenter - whose father, rocker Ozzy Osbourne, has had a long-running battle with drugs and alcohol - believes her dependence on prescription drugs is something hardwired into her genes.

Kelly - who is now drug free - told Britain's BBC Radio 5 Live: "I don't have any shadow of a doubt that addiction is a disease. It is in your genes."

Sharon Osbourne will never be free from bulimia. The "America's Got Talent" judge has suffered from the eating disorder since she was a teenager and while she now has it under control, she admits it she will always have issues with food.

Sharon - who had gastric band surgery in 1999 - said: "If I'm honest, I don't think I'll ever be totally free from that. It's much more under control but food for me will never be easy."

Sharon Osbourne believes she is successful because she is "short, fat and hairy." The TV star - who began her career as a rock manager - worked a lot harder to have a thriving career because of her imperfections.

Sharon - who has undergone multiple cosmetic procedures to improve her looks - told Psychologies magazine: "My achievements are down to my looks, or lack of them. I'm not putting myself down, that's the truth."

Jack Osbourne is obsessed with guns. The 23-year-old TV star is so "gun crazy" his father, legendary rocker Ozzy Osbourne, worries Jack will end up hurting himself.

He said: "Jack is gun crazy. Over here in the U.S. you can buy real guns. I have this horrible thing - I can see this movie in my head where he's messing around and shoots himself in the foot."
