Ashley Hebert and J.P. Rosenbaum, the second "Bachelorette" couple to ever walk down the aisle, will share a dramatic new chapter of their love story with millions of viewers when ABC televises their much anticipated wedding on THE BACHELORETTE: ASHLEY & J.P.'s WEDDING SUNDAY, DECEMBER 16 (9:00-11:00 p.m., ET) on the ABC Television Network. Get a sneak peek below!

Weeks of planning and anticipation culminate with former "Bachelorette" star Ashley Hebert and J.P. Rosenbaum declaring their love for one another before family, friends, past "Bachelor" and "Bachelorette" couples, stars and participants, who are all there to help them celebrate. The guest list includes Trista and Ryan Sutter, Jason and Molly Mesnick, Ali Fedotowsky, Jillian Harris, Deanna Pappas, Sean Lowe, Roberto Martinez and Ryan Park.

In the special, the couple, who were married on December 1 after J.P. proposed to Ashley on Bachelorette finale in Fiji in August 2010, let viewers in on all the exciting festivities. Ashley and J.P. will look back at their life since that romantic proposal and how they surprised both of their parents with the happy news of their wedding date. The couple is in for a shock when they meet with Mindy Weiss, their wedding planner, who has arranged a number of celebrity nuptials, and discover just how much will go into making their special day a day to remember.

Then follow Ashley to her dress fitting for her dazzling custom-made gown by famed red carpet dress designer Randi Rahm and watch the couple cut loose at their wild bachelor and bachelorette party weekend in Scottsdale, Arizona. J.P. and his friends get to let off steam in high performance vehicles and Ashley's group is surprised by a sexy pole dancer. Will Ashley try it herself?

The happy couple requested that CHRIS HARRISON officiate the wedding, but before he can agree, he has some tough questions of his own. Finally, it is the morning of their wedding day and both the bride and groom are preparing. J.P., all of his groomsmen and the fathers of the bride (both her father and stepfather) and groom are wearing Hugo Boss. A rapturous Ashley walks down the aisle to pop singer-songwriter Lisa Donnelly covering Elvis Presley's "Can't Help Falling in Love," as J.P., beaming, looks on, and the breathtaking ceremony begins before 200 guests at The Langham Huntington, Pasadena, an elegant, iconic landmark hotel in Southern California. As the couple walk back down the aisle as man and wife, Lisa sings "Here to Stay," which she wrote especially for Ashley and J.P. for this occasion.
