Don’t be fooled by the chain-smoking, booze-swigging character he plays on AMC’s "Mad Men." Jon Hamm is Don Draper’s antithesis. Off-screen, he stays fit with tennis and frequently hits the links—he also participated in this year’s MLB All-Star Legends and Celebrity Softball Game. He doesn’t smoke, either (only
herbal cigarettes for the show), and enjoys a vegetable-heavy diet, due in part to his vegetarian girlfriend who he says does most of the cooking.
