Rumor has it that Karlie Kloss will be included in the 2013 Pirelli Calendar! It's a huge deal for the 19-year old, being one of the younger models in the business.

Pirelli's 2012 Calendar featured Kate Moss, Lara Stone, Joan Smalls, Natasha Poly and more posing in the nude for photographer Mario Sorrenti. It's definitely NSFW and undoubtedly a man's favorite calendar.

Kloss has posed semi-nude for Allure and showed off her rack on Vogue Italia, so doing the Pirelli Calendar should go off without a hitch!
