Jack Osbourne diagnosed with multiple sclerosis

The reality TV star was diagnosed from tests taken when he lost 60% vision in his right eye earlier this year.

The diagnosis came three weeks after the birth of daughter Pearl, now two months old.

"The timing was so bad," he said. "I'd just had a baby, work was going great - I kept thinking: 'Why now?'"

He told Hello! that after first feeling angry and upset he has now taken an attitude of "adapt and overcome".

Ozzy, who was a notoriously heavy drinker and drug user during his years of rock’n’roll stardom, said he really felt for his son.

"If it was me, you'd think: 'Ozzy had a reputation and it caught up with him', but Jack is such a good guy."

MS is an incurable neurological condition that damages the nerves and affects the transfer of messages around the body.
