Congratulations are in order for Kevin Jonas and Danielle Deleasa. The couple, who got engaged in July, will officially become man and wife tomorrow.

Every Jonas Brothers fan on earth is freaking out over today’s big Jonas wedding. Danielle Deleasa is the first girl to wed a Jonas Brother and today is her big debut as Mrs. Jonas.

Kevin Jonas and Danielle Deleasa are tying the knot in New York on Long Island in the Oheka Castle estate.

Sources have somehow told Radar Online pretty much everything about the event. For example:

* It will take place at a private estate in Long Island called Oheka Castle, the same locale where Joey Fatone got married.
* Demi Lovato will be in attendance.
* The menu will include filet mignon, sea bass, chicken and a vegetable tart.

It’s unclear if Danielle will take Kevin’s last name, or if the private pair will release any wedding photos from the festivities.
