Veteran producer and director Ivan Reitman is set to direct an untitled romantic comedy starring Natalie Portman and Ashton Kutcher for Paramount Pictures, according to Variety.

The project's working title is Friends With Benefits. The script was penned by Elizabeth Meriwether.

The logline is being kept under tight wraps, although storyline generally revolves around the ease with which men and women become sexually involved, but have a far more difficult time establishing emotional bonds.

Paramount has already set a Jan. 7 release date for the film. Production will begin in May.
