Jack Osbourne to tie the knot

London: TV star Jack Osbourne is all set to get married to girlfriend Lisa Stelly. The son of Sharon and Ozzy Osbourne will tie the knot with Stelly, with whom he has five-month-old daughter Pearl, in Hawaii, reported Showbizspy. "They just sent the invites out and are asking guests to sign non-disclosure agreements," a source said. Jack, 26, recently said planning the wedding had helped him stay positive after he was diagnosed with multiple sclerosis. "It is something great to focus on. Even when I was at the hospital, we were discussing the plans. It is going to be great," he said. "After we had the baby we decided we didn`t want to waste any more time," Stelly said. PTI
