Kate Upton is the 2013 Sports Illustrated Swimsuit Issue cover girl! She posed in skimpy bikini bottoms in chilly Antarctica for the shot, which landed Kate in the coveted spot for the second year in a row. Kate rocked a tiny red suit for the 2012 issue, and her newest snap makes her the first SI swimsuit model to land back-to-back covers since Tyra Banks graced both the 1996 and 1997 publications. Kate spoke to People about her sexy Antartica cover shoot, saying it was "definitely the hardest shoot I've ever done." She continued, "The best as well – Antarctica is one of the most beautiful place I've ever been to. But I'm from Florida, so it was pretty painful." Kate's edition of SI is available on newsstands now.
