'Bachelorette' Ashley Hebert weds Long Island's J.P. Rosenbaum

"Bachelorette" star Ashley Hebert's wedding to Long Island's own J.P. Rosenbaum will air on ABC Sunday night at 9 in a two-hour special -- and Hebert confesses it wasn't the Roslyn-raised hunk she was thinking about when she sashayed down the aisle.

What was going through her mind?

" 'Wow, my train is so heavy. I'm not sure I can make it all the way up those steps,' " Hebert divulged this week during a media conference call with Rosenbaum, apologizing to him for her pragmatic thoughts. "Babe, I'm sorry, but that was the truth. It was so heavy."

In "The Bachelorette: Ashley and J.P.'s Wedding," the duo who fell in love in 2010 during season seven of "The Bachelorette" come full circle, tying the knot with Bachelor franchise host Chris Harrison officiating.

The wedding of the couple's dreams took place Dec. 1 at The Langham Huntington hotel in Pasadena, Calif. And let's clearly define "wedding of their dreams": Hebert's dress was created by celebrity designer Randi Rahm from ideas Hebert picked on Pinterest. And when Rosenbaum, 35, and Hebert, 28, shared their first dance to Matt White's "Love," the pop artist performed it in person.

During the special, viewers will see the couple meet with wedding planner Mindy Weiss and enjoy bachelor and bachelorette parties in Scottsdale, Ariz. Other famed members of Bachelor nation -- such as Sean Lowe, who stars in the upcoming season of "The Bachelor" and Emily Maynard -- appear during the ceremony.

To what must have been the horror of producers, no drama occurred, according to Hebert. But there was plenty of romance and fantasy -- other staples of the franchise.

"We got married under a chuppah. We broke the glass. We signed the Ketubah. I was wearing a yarmulke," Rosenbaum said. Viewers might see Hebert and Rosenbaum exchange wedding gifts -- he bought her a charm bracelet with a little dog on it (they have a Yorkshire terrier named Boo), a rose (um, Bachelorette fans, do we really need to explain this one?) and a toothbrush (she is a pediatric dentist, after all).

Incidentally, the duo also has a public registry on myregistry.com that includes the ability to donate to a charity such as New York Cares. They said the most unusual gift they've gotten from a fan was a homemade pair of earrings for Hebert with Boo's picture on them.

One scene viewers may not see on air: Harrison and a producer tie their ties together to form a limbo stick for guests on the dance floor.

Hebert and Rosenbaum -- or we should now say the Rosenbaums, as Hebert is taking J.P.'s last name -- plan to watch alone together from their Princeton living room. They're living in New Jersey while Dr. Rosenbaum -- "Sounds good, don't you think?" Hebert said -- finishes her residency at St. Charles Hospital for Children in Philadelphia and Rosenbaum continues his work in construction in Manhattan.

The Rosenbaums are only the second "Bachelor" couple to marry, following Trista Rehn and Ryan Sutter, who wed in 2003. (Some consider them the third couple, as Jason Resnick married a contestant from his season, just not the one he originally picked.)

The Rosenbaums said there's no "secret formula" explaining why they made it to the altar.

"It's really just like in life," J.P. said. "Some couples make it and some don't."
