Brooklyn Decker has signed on to the film adaptation of What to Expect When You're Expecting, based on the bestselling book. She will join Cameron Diaz and Jennifer Lopez who have already signed on to the project.
Decker is a swimsuit-model-turned-actress who first appeared in film as the love interest for Adam Sandler in Just Go With It.
She is set to play the perky wife of an older man who seems to have no problems with her pregnancy - and she's having twins! She is also set to appear in the upcoming board-game inspired film Battleship.
Directed by Kirk Jones, What to Expect is set to begin shooting this summer in time for a May 11, 2012 release.
