Anna Kendrick and Chace Crawford easily have one of the most heartbreaking story lines in What to Expect When You're Expecting, but the pair brought plenty of laughs to our recent chat during a press day for the project. The duo plays competing food-truck chefs in the film who end up in a serious — and seriously unplanned — relationship. Anna admitted she put a lot of elbow grease into prepping for the role but said she later discovered her effort was mostly wasted once the cameras were rolling. Chace also dished on the potentially romantic meal he's an ace at whipping up in the kitchen. We also talked about the dozens of babies crawling around the set and the "creepy" stand-in dolls they used in place of real infants. Check out our interview and catch What to Expect When You're Expecting when it hits theaters on May 18!
