The reality star and film-maker also revealed that the diagnosis was an emotionally traumatic time for him.
"While I was waiting for the final results, I got really, really angry," he 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".
Speaking to the magazine, 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 revealed he was angered by the news. "If it was me, you'd think: 'Ozzy had a reputation and it caught up with him', but Jack is such a good guy."
