Cameron Diaz got into character on the set of What to Expect When You're Expecting in Atlanta today. She wore a large prosthetic belly for the scene and also showed off her super toned arms in a tank. The actress made the trip to Georgia following an appearance at the Teen Choice Awards, where she picked up a surfboard for her work in Bad Teacher earlier this month. She's been busy traveling all Summer for both business and pleasure. Cameron popped up in Miami with boyfriend Alex Rodriguez, stopped in London to film Gambit, and also visited Mexico to promote Bad Teacher. Cameron's making the most of her time in Atlanta though, and she and her mom were spotted dining on Southern food just last week.
