Jonas Brothers - Kevin Jonas Married His Girlfriend Danielle Deleasa Yesterday (19.12.09).

The Jonas Brothers singer - who got engaged to former hairdresser Danielle in July - tied the knot at Oheka Castle, a chateau on an estate in Long Island, New York.

The wedding went ahead despite a blizzard threatening to ruin the nuptials, and was attended by 400 family members and friends, including Demi Lovato, who starred with The Jonas Brothers in 'Camp Rock'.

The 22-year-old musician said: "We're so happy that we're finally married and we were able to share the special moment with family, friends and loved ones."

Michael Russo, a celebrity event planner, said: "The snow only made it look more like a winter wonderland.

"Danielle looked like a princess. When she walked down the aisle in her strapless tulle and Chantilly lace Vera Wang gown... Kevin couldn't stop smiling."

Danielle - who was led down the aisle by her father, Thomas Deleasa - also wore a silk-and-crystal flower in her hair because she was wearing one when she met Kevin in the Bahamas in 2007.

Kevin's brothers, Joe, 20, and Nick, 17, served as his best men, while the bride and groom recited traditional vows and exchanged Jacob and Co. wedding rings they'd designed for one another.
