Sharon Osbourne - Sharon Osbourne Panics Over Son's Health

The 26 year old went public with his health battle in June (12) and his mother admits she is still struggling to come to terms with his condition.

Osbourne reveals she has been fussing over her son, much to his annoyance, and she's always worried whenever he feels sick.

She says, "I've become even more of a control freak. I think I'm driving him nuts. He's got a headache and I'm all, like, 'Go to the doctors. I'll drive you myself.' And I'm fussing and asking him what he's eating and all of that kind of thing. He's as good as married and he has a baby and he left home about a hundred years ago and I'm still fussing over him."

Meanwhile, Osbourne also reveals she was pleased to hear from her former The X Factor co-star Simon Cowell after Jack's news hit headlines. She adds, "One of the first people to reach out to me when Jack was diagnosed with MS was Simon. And that meant very much to me. Because it meant maybe he loves me, just a little bit."
