Kevin Jonas is a married man!
The musician, 22, and Danielle Deleasa, 23, tied the knot during a snow blizzard Saturday in Long Island, New York.
The ceremony took place at Oheka Castle with 400 guests including actress/singer Demi Lovato. Brothers Nick and Joe served as Kevin's best men.
Danielle, a former hairdresser, wore a Chantilly lace Vera Wang gown and a silk-and-crystal flower in her hair.
Jonas popped the question in July when he surprised her at her New Jersey home and asked her to marry him with a cushion-cut diamond ring from Jacob & Co.
