The Purity Ring Is Off! Kevin Jonas Weds!

And they're married!

Kevin Jonas and longtime girlfriend Danielle Deleasa were wed in a private ceremony at Oheka Castle in Long Island on Saturday night!

"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 happy couple has told reporters.

Deleasa walked down the aisle in a "strapless tulle and Chantilly lace Vera Wang gown," and Jonas reportedly could not keep a smile off his face as his bride made her way to the alter.

So, so cute!

Kevin and Danielle recited traditional wedding vows with Joe and Nick standing beside their brother as his best men.

The wedding was originally threatened by the winter weather taking the East Coast by storm, but guests, including Demi Lovato enjoyed the wedding and reception from under heated tents dressed up to look like a "winter wonderland."

And we're sure the happy couple had tons of fun on their wedding night as well!

(Wink wink)

Congrats!
