Up All Night's final show without a studio audience will be a special one as the series flashes back to the disastrous pre-baby wedding of Chris (Will Arnett) and Reagan (Christina Applegate).

The episode, titled "The Wedding" and set to air at year's end, will see the return of Blythe Danner as Reagan's mom, Angie, and introduce Mimi Kennedy (Dharma & Greg) and Bob Gunton (24, Royal Pains) as Chris' parents, Sally and Tom.

The happy couple will then get a super long honeymoon before the revamped series returns in spring 2013 in front of a live studio audience.
