After announcing their engagement last September and welcoming daughter Pearl in April, and the lovebirds tied the knot in Hawaii on Sunday.

The couple started dating in April of 2011, and after Osbourne's shocking multiple sclerosis diagnosis earlier this summer, a source close to the couple told Us Magazine that Stelly was committed to helping him cope with the disease. "Lisa makes sure he's healthy -- eating right and exercising," the insider tells the mag. "They love staying active as a family."
