Is Katherine Heigl going from rom-coms ... to rom-drams?

According to E! Online, the Grey's Anatomy actress is set to star in Life as We Know It, a film about two singletons who must come together to raise an orphaned child.

And fall in love, perhaps?

The film, which is set to be directed by Greg Berlanti, sounds like it might be a project that is ripe with dramatic possibility, but the really interesting thing about it? The Emmy-winning actress will also be co-producing the film with her mother, Nancy Heigl.

Nancy and Katherine Heigl recently formed a production company together.

Ending months of rumors, Katherine Heigl is said to have signed a deal to return for the sixth season of Grey's Anatomy, though the star herself has not confirmed it.
