The cat's out of the bag...Jack Osbourne is getting married this weekend! The Osbourne family was trying to keep the wedding on the down-low but when it comes to celebrity weddings it's nearly impossible to keep it so hush-hush that no one in the media finds out about it.

Jack will be marrying the mother of his 5 month old daughter, Lisa Stelly in Hawaii this weekend. According to the 'New York Post' the invites just went out and in them they have asked guests to sign a non-disclosure agreement. That's really all we have heard so far but I'm sure as people start arriving for the celebration more details will surface.

Congratulations to Jack and Lisa!
