About the show:

Best friends Lizzy (Elisha Cuthbert, "Happy Endings") and Luke (Nick Zano, "2 Broke Girls") are like family.

As kids, they saw each other's parents go through divorce and have ever since formed an inseparable bond. Now, all grown up and still single, they've decided to start a family of their own, but in a non-traditional way. Lizzy, who is a lesbian, wants to raise a child with Luke by her side.

Then one night, Luke falls for Prudence (Kelly Brook, "Smallville"), a free-spirited British girl who's due to go back to England in a matter of days. Then, just as Lizzy discovers that she's actually pregnant, Luke announces that he and Prudence have gotten married and in an instant - a different kind of family is born.

The cast also includes Brandon Mychal Smith ("Get On Up,"), Rebecca Corry ("2 Broke Girls") and Chris Williams ("Satisfaction").

Writer Liz Feldman ("2 Broke Girls") and Jeff Kleeman ("The Change Up") serve as executive producers with Ellen DeGeneres ("The Ellen DeGeneres Show"). Scott Ellis ("2 Broke Girls") serves as executive producer/director on the pilot episode. "One Big Happy" is a production of Warner Bros. Television and A Very Good Production.
