Sharon Osbourne Breaks Down On TV As She Opens Up About Son Jack's Multiple Sclerosis (VIDEO)

We were all shocked at yesterday's news that Jack Osbourne has been diagnosed with multiple sclerosis and it's understandably something that his mum Sharon is finding very hard to come to terms with after breaking down on a US TV show.

Sharon was recording an episode of the American panel show, The Talk, when she broke down in tears after being asked about Jack's diagnosis.

"[Jack's] doing really, really good and I want to thank everyone for all their texts and goodwill and love they send to us," she said.

"It's been amazing for Jack because I really believe that... vibes and prayer really helps."

"And what I'm doing right now is not helping because I'm just feeling sorry for myself and that is no good. So we have to think positively and get on with this show."

Jack, 26, learned of his illness just weeks after the birth of his daughter Pearl Clementine. He was found to have the incurable autoimmune disease after losing 60% of the vision in his right eye.

Sharon also revealed on the show that Jack will appear this Wednesday to discuss his diagnosis.
