Ashley Hebert, J.P. Rosenbaum's Wedding: ABC Sets A Date For 'Bachelorette' Special

It's official: Ashley Hebert and J.P. Rosenbaum are getting married on TV!

"The Bachelorette" couple, who got engaged in August 2011 following the show's 7th season, will be tying the knot in an on-air special -- and their wedding date has been revealed.

"The Bachelorette: Ashley and J.P.'s Wedding" is slated to air Dec. 16 on ABC, the network announced Friday.

And get this -- host Chris Harrison will be officiating the nuptials, which will be attended by a handful of "Bachelor," "Bachelorette" and "Bachelor Pad" stars.

To name a few: Trista and Ryan Sutter, who got married in their own TV wedding special, will be present, as well as fellow married "Bachelor" couples, Jason and Molly Mesnick and Blake Julian and Holly Durst.

What we can assume is that Brad Womack and Bentley Williams will NOT be on the guest list -- sorry guys.
