"What To Expect When You're Expecting" hits theaters May 18th, so premieres abound. Yesterday, there was one at the AMC theater in Lincoln Square, in New York City. Brooklyn Decker, who appears in the film (ed note: what actor doesn't appear in this film? Seriously) was on hand in a sexy white dress. It showed off just enough of her body to see why the super model was cast in the film. Well, besides her acting talent, right?
