Former reality-TV star Jack Osbourne and his fiancee, Lisa Stelly, the mother of their 5-month-old daughter Pearl, have been married in Hawaii.

Osbourne, 26 -- the son of heavy-metal rock legend Ozzy Osbourne and former "America's Got Talent" judge Sharon Osbourne -- and aspiring actress Stelly said their vows Sunday before 48 guests, according to Hello! magazine, which first reported the wedding. Jack Osbourne's sister Kelly served as a bridesmaid.

Osbourne's rep confirmed the news.

He and Stelly met in April 2011 and became engaged that September, according to Us Weekly. Their daughter was born April 24.

In June, Osbourne revealed that he was diagnosed with multiple sclerosis, an autoimmune disease. His mother quit NBC's "America's Got Talent" after charging that, because of the MS, the network had dropped her son from the planned cast of the military-style competition "Stars Earn Stripes."
