The 26-year-old TV star and model-and-actress Lisa Stelly tied the knot in the
Kona-Kohala coast of West Hawaii on 07.10.12, HELLO! magazine have confirmed.
The nuptials were witnessed by 48 guests, including the couple`s six-month-old daughter Pearl, Jack`s famous parents Ozzy and Sharon Osbourne, sister Kelly Osbourne - who was a bridesmaid - and her boyfriend Matthew Mosshart.
Although it was speculated last week that the couple - who got engaged last September - were to marry over the weekend, Jack took to twitter to play down the reports.
He wrote: "I love how going to Hawaii with my mum for her 60th has turned into my wedding. Hahaha people are funny."
The happy news comes months after Jack revealed he had been diagnosed with multiple sclerosis soon after Pearl`s birth.
He said recently: "Honestly, I`m fine. Ultimately that is the toughest thing with this disease that I`m learning, one minute you can be fine, and the next I went blind in my right eye. It`s a completely unpredictable disease."
Lisa added: "I think me and Jack are doing better than everyone else, honestly.
"We`re just really trying to stay positive and we don`t really have much time to be sad, because we have diapers to change and a little girl to look at and smile at. We`re just having fun. He`s going to be OK."
