Jennifer Lopez has come aboard to star in the romantic comedy "Plan B" for CBS Films.

Kate Angelo penned the spec, which centers on a single woman who conceives twins through artificial insemination (her Plan B) only to meet the man of her dreams (her Plan A) on the very same day.

Todd Black, Jason Blumenthal and Steve Tisch are producing via their Escape Artists banner.

The producers are currently seeking a director as well as the male lead, with production scheduled to start in the spring.

"Plan B" is one of the first CBS Films projects to get a green light.

Black said that even with the pregnancy theme the movie had the potential to appeal across gender lines. "I'm really aiming to make a movie that's relatable to men and women. They can laugh super-hard and walk away being OK with their choices."

CBS Films topper Amy Baer noted that the material would take Lopez back to her core strength of the romantic comedy and also noted that the hyphenate giving birth to twins of her own would bring an added dimension to the role.

Lopez has starred in a number of comedy hits, including "Maid in Manhattan" and "Monster-in-Law". She had taken a break from her acting career to focus on her music career and on giving birth to her twins, which she did earlier this year, but is set to return to the big screen in the heist picture "The Governess" for Columbia, due out in December 2009.
