"Bachelorette" stars Ashley Hebert and J.P. Rosenbaum's wedding special to air Dec. 16 on ABC

Save the date! ABC announced it will air "The Bachelorette" stars Ashley Hebert and J.P. Rosenbaum's wedding on Sunday, Dec. 16 at 9 p.m.

At the reality couple's request, Chris Harrison will officiate their nuptials, since he hosts the show where they first met and fell in love.

Hebert and Rosenbaum are only the second "Bachelorette" couple to make it to the altar. (Season 1's Trista and Ryan Sutter are still happily married with two children.)

"The Bachelorette: Ashley and J.P.'s Wedding" gives viewers a sneak peek into Hebert's custom-made wedding gown fitting, their wedding planning, and of course their bachelor and bachelorette parties.

The guest list also includes former "Bachelor" and "Bachelorette" contestants, in addition to the couple's families and friends.

"The Bachelorette: Ashley and J.P.'s Wedding" debuts Sunday, Dec. 16 at from 9 to 11 p.m.
