Swimsuit model-turned actress Brooklyn Decker (Just Go With It) will join director Kirk Jones’ (Everybody’s Fine) adaptation of the bestselling book What to Expect When You’re Expecting. Decker joins a cast that already features Cameron Diaz, Jennifer Lopez, and Isla Fisher. Per Deadline, the actress will make a turn as the wife of an older man who makes carrying and giving birth to twins seem like a breeze, and is hated by her peers as a result. The pic begins shooting this summer and is aiming for a May 11th, 2012 release. In addition What to Expect, Decker also stars alongside Liam Neeson, Alexander Skarsgard, Taylor Kitsch, Josh Pence, and Rihanna in director Peter Berg’s Battleship which is scheduled to hit theaters the week after What to Expect on May 18th.
