Thirty-seven years ago today, the world was gifted with the birth of Heidi Klum. For almost two decades, the gorgeous German-born runway model, Victoria Secret Angel, and TV host has probably stripped down to pose in her birthday suit almost as many times as Seal gets asked to never sing "Kiss from a Rose" again. She once told The Independent she "comes from a place where I am used to running around nekked." To our delight, Klum has quite a reputation for getting nekked for high-profile pictorials. Even though she's beginning to enter her cougar years, Klum continues to dazzle us as one of the sexiest women of our generation. In honor of Klum's 37th birthday, we've compiled 37 topl*ss photos of Klum, ranging from GQ, above, to Esquire to, of course, the Sports Illustrated Swimsuit Issue, where most of us first met Heidi. Since we've been oogling over Klum on TV and in glossy magazines for almost 18 years, we believe that showing off her physical assets is really the only appropriate birthday tribute. NSFW-ish photos after the jump (she's topl*ss in all of them, but you'll have to look really closely to see any n*pples).
