Kevin Jonas, one-third of the Disney rock trio The Jonas Brothers, married his girlfriend of two years, Danielle Deleasa, on Saturday afternoon. The couple exchanged wedding rings in an outdoor ceremony right before a huge blizzard ravaged Long island.

The event took place in Cold Spring Harbor at Oheka Castle – a nearly 100-year-old French-style chateau. In attendance were the 22-year-old groom`s brothers, best men and bandmates, Joe and Nick Jonas, and Disney entertainer Demi Lovato. About 400 relatives and friends attended.

Jonas met his bride, a 23-year-old ex-hairdresser, during a family vacation to the Bahamas two years ago. He surprised her last July by showing up on her New Jersey doorstep with a three-carat solitaire cushion-cut diamond engagement ring surrounded by 210 round, brilliant-cut pave diamonds. He designed the ring himself, with help from Jacob the Jeweler. "She said yes, yes, yes like 500 times super fast in a row," he reminisced.

Danielle wore a Vera Wang gown made of Chantilly lace and a designer silk-and-crystal flower in her hair during the ceremony.

Celebrity event planner Michael Russo said that it had begun snowing during the wedding, enhancing the `winter wonderland` theme. Russo created a fairy-tale forest theme that included heated white tents with 14-foot trees and crystals made to look like icicles.
