Next on ‘Accidentally on Purpose’: It Happened One Christmas

It’s time to meet the parents during “It Happened One Christmas,” the fresh December 14 episode of CBS’ Accidentally on Purpose.

The parents in question are Billie’s, who she suspects won’t react too well to the news that she’s living with her baby daddy Zack.

So, while Billie tries to hide that critical detail from her parents Lara (Worst Week’s Nancy Leneham) and Edward (Hunter’s Fred Dryer) in order to avoid ruining the Christmas festivities, Abby’s husband Nick tries to win over the sisters’ father by impressing him.

Sneak a quick peek at “It Happened One Christmas” in the following promo.
