Rocker Ozzy Osbourne and his wife, former X Factor judge Sharon, are reeling after their son Jack was diagnosed with multiple sclerosis (MS).


Jack (26) — who has recently become a father — was found to have the incurable disease after a frightening spell in which he lost 60 per cent of the vision in his right eye.


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.” And Black Sabbath hellraiser 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.”
