The reality television star Jack Osbourne has been diagnosed with multiple sclerosis, it was revealed today.

The 26-year-old son of Black Sabbath singer Ozzy and former X Factor judge Sharon Osbourne found out he had the incurable disease when he went for tests after losing 60 per cent of the vision in his right eye.

He went for tests in the same hospital in which his fiancé Lisa Stelly had given birth to their two month old daughter Pearl just three weeks earlier.

"While I was waiting for the final results, I got really, really angry," Jack said.

"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."

To combat the incurable disease, Jack plans to use a combination of drug treatments, holistic therapies and lifestyle changes.

Multiple sclerosis is not fatal, but some complications which can arise from more severe MS, such as pneumonia, can be.

As a result, the average life expectancy for people with MS is around ten years lower than the population at large.

The extreme sports enthusiast’s parents are struggling to come to terms with the fact their son has multiple sclerosis – an autoimmune disease that affects the brain and the nervous system.

Sharon said "I keep thinking, 'what did I do wrong? What did I eat or drink when I was pregnant?' I feel like it's somehow my fault."

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