According to the New York Post, Ozzy Osbourne's son Jack will marry his fiancée Lisa Stelly this weekend in Hawaii.
"They just sent the invites out and are asking guests to sign non-disclosure agreements," an unnamed source told the Post.
Jack, 26, revealed in an interview with Hello! magazine that he was diagnosed with multiple sclerosis — the incurable neurological disease which attacks the brain and spinal cord — two weeks after he and his fiancée welcomed their daughter, Pearl Clementine.
"I was just angry and frustrated and kept thinking, 'Why now?'" he told Hello! "I've got a family and that's what's supposed to be the most important thing."
"The timing was so bad," he said. "I'd just had a baby, work was going great ... I kept thinking: 'Why now?'
"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 realized: 'Being angry and upset is not going to do anything at this point — if anything it's only going to make it worse,'" he told Hello! "'Adapt and overcome' is my new motto."
