In a setting fit for a Disney prince and his princess, Kevin Jonas married Danielle Deleasa Saturday night at Oheka Castle, a turn-of-the-century French-style chateau, on a sprawling estate in Long Island.
"We're so happy that we're finally married and we were able to share the special moment with family, friends and loved ones," the couple tells PEOPLE.
Though a blizzard threatened the festivities, the wedding attended by 400 family members and friends, including Demi Lovato, went forward as scheduled.
"The snow only made it look more like a winter wonderland," said Michael Russo, a celebrity event planner of Roses-n-Lollipops, who for Saturday's event created a fairytale forest under heated white tents, complete with 14-foot trees draped in hydrangeas and crystals made to look like icicles.
"Danielle looked like a princess," he said. When she walked down the aisle in her strapless tulle and Chantilly lace Vera Wang gown, "Kevin couldn't stop smiling," said Russo.
The bride was escorted down the aisle by her father, Thomas Deleasa. Danielle, a former hairdresser, wore a silk-and-crystal flower in her hair designed by Denise Leli, because she was wearing one when she met Kevin in the Bahamas 2007.
With his brothers, Joe and Nick serving as his best men, Kevin, 22, and Danielle, 23, recited traditional vows and exchanged Jacob & Co. wedding bands they designed for one another.
"Kevin has said many times he feels like he met his princess," says Russo. "To see them together you can feel the warmth and the love all around them. They are just perfect for each other."
After the ceremony, guests were to be treated to a smorgasbord of Caribbean, Asian and Italian among other dishes.
