Jack Osbourne, son of rock and roll royalty, Black Sabbath frontman Ozzy, has spoken of his recent multiple sclerosis diagnosis.

The son of Black Sabbath frontman Ozzy Osbourne has revealed he is suffering the condition in a new interview with Hello magazine. He was diagnosed earleir this year after losing 60% of vision in his right eye earlier this year.

"The timing was so bad. I'd just had a baby, work was going great - I kept thinking: 'Why now?'" He told the magazine. "While I was waiting for the final results, I got really, really angry.

"Then I got really sad for about two days, and after that I realised, being angry and upset is not going to do anything at this point - if anything it's only going to make it worse. 'Adapt and overcome' is my new motto."

Ozzy Osbourne has also spoken of his son's diagnosis, saying it might be expected for him to suffer the illness, but not 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," said Ozzy.

Jack Osbourne was diagnosed with the incurable condition three weeks after becoming a father. Symptoms include tiredness, temporary blindness, loss of co-ordination and difficulty with speech.
