Jack Osbourne set to wed this weekend

Ozzy Osbourne's son Jack is reportedly set to marry his fiancee in a romantic wedding this weekend.

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.

He admitted in June 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."
