"I knew that my princess needed her glass slippers and her castle," Jonas told PEOPLE of the nuptials.
"I always wanted my wedding to have that princess feel," adds the new Mrs. Jonas. "I couldn't have imagined this," she says of her lavish wedding Dec. 19 at Oheka Castle in Huntington, New York.
Despite a blizzard blanketing the roads around the castle, the wedding went forward without a hitch, and the bride, escorted by her father Thomas "Bucky" Deleasa, walked down the aisle to "Bella Notte," from Lady and the Tramp, played on the guitar by a friend of the Jonas family. "I'm an Italian girl. It just fit me and my dad," said Danielle of the song choice.
The groom's father Kevin Jonas Sr., an ordained minister, officiated along with Danielle's childhood pastor, Rev. Ron DePasquale Jr. After reciting traditional vows, the couple exchanged Jacob & Co. wedding bands that they designed for one another.
"I've never seen a more beautiful bride," said Kevin of Danielle, who he calls his "Jersey Girl" and who wore a strapless tulle and Chantilly lace Vera Wang gown at the ceremony.
