As expected, Jack Osbourne exchanged vows with Lisa Stelly last weekend during an intimate ceremony in Hawaii. US Weekly reports the 26-year-old son to Sharon and Ozzy Osbourne said "I do" on Sunday, about one year after announcing he was engaged.

E! News reports the wedding took place on the Kona-Kohala coast, at the Four Seasons Hotel in Hualalai. Only close friends and family were in attendance, including Jack's sister Kelly who served as a bridesmaid. On Friday, Jack Osbourne tried to convince his followers on Twitter that the trip was for his mother's 60th birthday.

"I love how going to Hawaii with my mum for her 60th has turned into my wedding. Hahaha people are funny," he tweeted.

There was an effort made to keep the wedding a secret, but those attempts clearly failed as numerous sources talked to tabloids, seemingly in the face of the couple's non-disclosure agreement they asked guests to sign. Osbourne and Stelly have a daughter together in 5-month-old Pearl. Shortly after her birth, the younger Osbourne revealed he'd been diagnosed with multiple sclerosis (MS).
