Photos of pin-up girls have come a long way since Betty Grable, the much-fawned-over 1940s sex bomb who graced the foot lockers of many a brave American solider in World War II. Thanks to magazines like Esquire, Vanity Fair, and Playboy, classy and patriotic photos of voluptuous All-American women have accompanied U.S. soldiers into combat for most of the 20th and 21st Century's wars and conflicts. In honor of BroBible's Military Week, here are 25 modern-day celebrity smoke shows who have rocked their best vintage "remind-the-G.I.s-what-they're-fighting-for" looks for a throwback pin-up photo shoot.
