Jack Osbourne and Lisa Stelly

It's been quite the year for Jack Osbourne. The son of Ozzy and Sharon got engaged to love Lisa Stelly last September, welcomed daughter Pearl in April, and was diagnosed with multiple sclerosis in June. And now? Osbourne is officially a married man.

The former reality star, 26, tied the knot with aspiring actress Stelly in an intimate Hawaiian ceremony Sunday, a source confirms to Us Weekly.

The couple first began dating in April 2011. After Osbourne's shocking MS diagnosis earlier this summer, a source close to the pair told Us Stelly was committed to standing by her man, and helping him cope with the disease.

"Lisa makes sure he's healthy -- eating right and exercising," says a friend of the duo. "They love staying active as a family."

Jack is also "a great influence on [Lisa]," another source shares. And their "stable" bond is "no drama," the source adds.

Jack and Lisa's nuptials won't be the only milestone the Osbourne family celebrates while they're in Hawaii: they'll most likely fete Jack's mom Sharon, too, as "The Talk" host turns the big 6-0 on Tuesday.
