The cast of director Kirk Jones’ (Everybody’s Fine) baby book adaptation What to Expect When You’re Expecting keeps growing, as Chris Rock and Anna Kendrick have just signed on. The Love Actually-esque movie will follow six expectant couples through the ups and downs of pregnancy. Lionsgate announced that Kendrick will play a woman who reunites with an old flame following a turf war between their food trucks.

Per Deadline, Rock will play the leader of a group of expectant fathers who “lectures them on what it's really like to have a baby and become a father.” Rock and Kendrick join a cast that includes Cameron Diaz, Jennifer Lopez, Isla Fischer and Brooklyn Decker. Filming begins this summer, with What to Expect When You’re Expecting slated for a May 11th, 2012 release.
