Rodrigo Santoro has become the latest to join the cast of What to Expect When You're Expecting for director Kirk Jones.

The actor will portray the husband of Jennifer Lopez in this adaptation of Heidi Murkoff's best-selling book. The movie will tell the interconnected stories of seven women who are expecting their first child. Jennifer Lopez, Cameron Diaz, Brooklyn Decker, and Anna Kendrick have already signed on to play four of the seven women. Chris Rock is also in talks to join the cast, along with Glee star Matthew Morrison.

Kirk Jones is directing What to Expect When You're Expecting from an adapted screenplay by Heather Hach and Shauna Cross (Whip It!).

Production is slated to begin later this summer, on location in Atlanta.
