This year's Sports Illustrated Swimsuit cover model is -- Kate Upton. Again. Upton repeats on the S-I cover for the second straight year. The 2013 S-I cover shot was taken in Antarctica, with Upton wearing only a white, fur-lined parka and a bikini bottom. She says it's the most she's wearing in the whole issue. The 50th anniversary S-I Swimsuit issue is on sale today.
