True Blood star Deborah Ann Woll has joined the cast of Are We Officially Dating? for writer-director Tom Gormican (Movie 43).

We reported in August that Zac Efron signed on to star as one of three male friends who make a pact to remain single. Of course, the plot thickens when soon thereafter, each guy meets his soul mate. Deborah Ann Woll will play the ex-wife of one of the men in this trio.

Tom Gormican is directing from his own original screenplay, which landed on the Black List in 2010. Justin Nappi and Kevin Turen are producing for Treehouse Pictures, along with Scott Aversano and Andrew O'Connor. Production is scheduled to begin next month.

Deborah Ann Woll was recently seen in the indie comedy Ruby Sparks, alongside Paul Dano and Zoe Kazan.
