Jack Osbourne reportedly tied the knot over the weekend.
The couple reportedly exchanged vows in front of family members in a ceremony in Hawaii, according to the entertainment news site. Osbourne, 26, announced his engagement to Stelly in September 2011. In April, the couple welcomed their first child, a daughter named Pearl Clementine.
Stelly is a model and aspiring actress and has appeared in Green Day's "21 Guns" music video and on "The Howard Stern Show" with Osbourne.
In June Osbourne revealed that he had been diagnosed with multiple sclerosis. He was diagnosed two weeks after his daughter was born.
Celebrities who have been diagnosed with the disease include comedian Richard Pryor, former mouseketeer and actress Annette Funicello, talk show host Montel Williams and actress Teri Garr.
Osbourne and his family starred in the MTV reality series "The Osbournes," which ran between 2002 and 2005 and depicted the family's wacky home life, as well as frequent squabbles between the Osbourne siblings Jack and Kelly.
Ozzy and Sharon Osbourne are also parents to a 29-year-old daughter, Aimee, who did not appear on the show.
