New CBS Sitcom: ‘Accidentally on Purpose’ Premiere Preview

It’s almost time to check out the September 21 series premiere of CBS’ latest original sitcom Accidentally on Purpose, starring former Dharma & Greg lead actress Jenna Elfman.

During the debut pilot episode…

We meet central character Billie (Elfman), a newspaper film critic who recently broke up with her boyfriend, only to immediately get pregnant afterwards by so-called accident during a one-night stand with a younger man named Zack (Jon Foster, Windfall).

Based on the hit Mary F. Pols memoir, the series follows Billie as she decides to keep her baby and then arranges with the father to live together as platonic roommates.

As expected, however, that setup leads to further complications, such as when Billie realizes that Zack and his immature friends have a very different lifestyle than she does, leaving her to wonder if her newborn will be the only child in the house.

Also starring on the newcomer are former Ugly Betty regular Ashley Jensen as Billie’s free-spirited best friend Olivia, Lennon Parham (Parks and Recreation) as Billie’s married little sister Abby, Melrose Place and Swingtown alum Grant Show as Billie’s current boss and commitment-phobic ex-boyfriend James, and Nicolas Wright (The Business) as Zack’s freeloading buddy Davis.

Sneak a peek at the 8:30pm ET series premiere in the following preview clip.

Accidentally on Purpose airs Mondays on CBS at 8:30pm ET.
