Jennifer Lopez has signed on to star in Plan B, the romantic comedy exploring fertility themes for CBS Films.

According to Variety, the story was penned by Kate Angelo and centers on a single woman (Lopez) who turns to artificial insemination to answer her ticking biological clock only to meet the man of her dreams on the same day as her positive pregnancy test results.

Producers and CBS Films are looking to tap a director for the project by the end of January, if not sooner.

The project, which is scheduled to shoot in April or May, will mark Lopez's return to the bigscreen after taking a couple of years off to give birth to twins.
