Ozzy Osbourne - Jack Osbourne Set For Weekend Wedding

The reality TV star will marry Lisa Stelly, the mother of his five-month-old daughter Pearl, at a ceremony in Hawaii, according to New York Post gossip column Page Six.

A source tells the publication, "They just sent the invites out and are asking guests to sign non-disclosure agreements."

The groom-to-be sparked speculation his nuptials were imminent after he threw a bachelor party in Las Vegas last month (Sep12).

He admitted in June (12) that planning the event had given him a boost after he was diagnosed with multiple sclerosis, insisting, "It's something great to focus on. Even when I was at the hospital, we were discussing the plans. It's going to be great."
