Congrats are in order to Jack Osbourne and the rest of the Osbourne family, which of course includes dad, Prince of Darkness Ozzy, and mom, Sharon. Osbourne married fiancée Lisa Stelly in Hawaii on Sunday, Oct. 7.

Osbourne, 26, and Stelly welcomed daughter Pearl in April of this year and have now officially become husband and wife.

Rumors began to swirl that the two were planning to swap vows when they headed off to Hawaii last week, leading Osbourne to dismiss the talk via Twitter, saying the family had gone on holiday to celebrate matriarch Sharon's 60th birthday, which is tomorrow, Oct. 9. He tweeted: "I love how going to Hawaii with my mum for her 60th has turned into my wedding. Hahaha people are funny."

The happy couple exchanged rings in a ceremony in front of 48 guests on the Kona-Kohala coast.

Jack's sister Kelly served as a bridesmaid.

It's been an eventful year for Jack Osbourne. In addition to becoming a father for the first time and now marrying his beloved, he also went public with the fact that he was diagnosed with multiple sclerosis earlier.
