Heigl, who has just been re-upped for her TV series Grey's Anatomy, has also scored a starring role in the upcoming big-screen romance Life as We Know It, according to Variety.

The movie tells the tale of two unattached adults whose worlds are turned upside down when their mutual best friends die in an accident and name them as caregivers for their orphaned daughter.

Katherine and her mother, Nancy Heigl, will also be executive-producing the project. Directing the movie will be Greg Berlanti, known for his work on TV's Dirty Sexy Money, Brothers and Sisters and Dawson's Creek.
