the son of Ozzy and reality TV star, has been diagnosed with multiple sclerosis.

The star was talking to Hello! magazine and said that ‘While I was waiting for the final results, I got really, really angry.

The timing was so bad. I’d just had a baby, work was going great – I kept thinking, “Why now?”

‘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.’

The 26-year-old recently became a father for the first time and he discovered he had the disease after losing 60 per cent of vision in his right eye.

His fiance Lisa has been very supportive. Lisa gave birth to their daughter, Pearl, two months ago.

Lisa told Hello! ‘Jack will have to change his life for the better – get healthier, not get stressed.’

Sharon and Ozzy Osborne told how they are struggling to come to terms with the diagnosis.

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.

Father Ozzy added: ‘If it was me, you’d think: “Ozzy had a reputation and it caught up with him,” but Jack is such a good guy.’

Sister Kelly took to her Twitter page this morning to urge fans to support her sibling, writing: ‘Please support my brother @mrjacko in not only his bravery but honesty! i love you so much jack & I’m so proud of you!’

After it was made public, Jack tweeted: ‘Thank you all so much for the kind and inspirational words. It means a lot. #adaptandovercome.’
