Ashley Hebert and J.P. Rosenbaum's December wedding special now has an airdate.

ABC has announced The Bachelorette: Ashley and J.P.'s Wedding air Sunday, December 16 from 9-11PM ET/PT.

The seventh-season The Bachelorette couple's wedding will be officiated by show host Chris Harrison, and former bachelors and bachelorettes of the franchise will attend the ceremony in addition to Hebert and Rosenbaum's family and friends.

According to the network, the special will cover Hebert and Rosenbaum's wedding ceremony as well as all the events leading up to it -- including the dress fittings for Hebert's custom-made gown, the couple's meetings with their wedding planner, and their bachelor and bachelorette parties.
