Sharon Osbourne Cries About Jack Osbourne's Multiple Sclerosis on 'The Talk'

Jack was diagnosed with the autoimmune disorder a few weeks ago after losing most of the sight in his right eye.

"Adapt and overcome" became his motto, he told HELLO!, after spending a few days depressed and angry. On the flipside, Sharon wondered if perhaps his disorder was her fault: "What did I do wrong? What did I eat or drink when I was pregnant?"

The Talk moderator, Julie Chen, told viewers about Jack's MS diagnosis, while tears streamed down Sharon's face.

"He's great, he's doing really really good. I want to thank everyone for your goodwill and messages," she said between sobs. "Just thank you to everyone for all their good wishes it’s been amazing for Jack, 'cause I really believe that vibes of prayer help."
