SI Swimsuit 2013 Preview
Kate Upton's Sports Illustrated Swimsuit Issue cover is very hot – but during her photo shoot in Antarctica, all the model could think about was the freezing cold.
"It was definitely the hardest shoot I've ever done," Upton, 20, tells PEOPLE. "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."
