Earlier today, we reported that model-turned-actress Brooklyn Decker would star in WHAT TO EXPECT WHEN YOU’RE EXPECTING as a perky woman named Skyler, whose pregnancy with twins goes without a hitch. Just hours later, it’s been revealed that two more actors have signed on for roles in the feature.

Deadline Hollywood updated its original story about Decker with news that Anna Kendrick will star in the Kirk Jones film as Rosie, who becomes pregnant after having an encounter with her ex. Deadline Hollywood also reports that Chris Rock has come on board to star as Vic, a man who acts a mentor to several fathers-to-be by discussing fatherhood with them.

Kendrick impressed the critics with her performance in Jason Reitman’s UP IN THE AIR. She took on an extremely tricky role with ease and confidence, providing an uncanny balance between the hilarity and the emotional weight of the film. While her role in WHAT TO EXPECT WHEN YOU’RE EXPECTING probably isn’t quite as demanding, we can expect her to fit in wonderfully with the cast.

Meanwhile, Rock is an incredibly talented comedian who has also had some great moments in comedic acting. Seeing his take on this mentor-like role will definitely be a treat. It'll be exciting to see who gets cast to play the fathers under his guidance.

WHAT TO EXPECT WHEN YOU’RE EXPECTING is currently slated to hit theaters on May 11, 2012, with filming to begin this summer.
