NSFW: World's Hottest Math Teacher Strips Naked for New Photoshoot

Pietro Boselli went viral last year when a student at the University of College London snapped photos of his teacher and posted them online. The hunky smarty was dubbed the world's hottest math teacher and eventually became the face of Armani.

While the 27-year-old teacher has a PhD in engineering, Boselli continues to model. For his latest gig, the Italian-born stallion, who earned a contract with Models 1, recently teamed up with photographer Philippe Vogelenzang for a racy new photoshoot, U.K. publication Attitude reports.

For a spread in Ladies & Gents No. 57 Boselli appeared completely nude opposite of model Ymre Stiekema. The pics show the teacher baring his bum in several shots.
