Kate Upton has done it again. She's landed on the cover of the Sports Illustrated Swimsuit Edition.She was the 2012 cover girl too. It's the first time since Tyra Banks did it in the mid-'90s that a model has gotten the honor back to back years.

After the photo was revealed Friday, Kate tweeted, "I look...cold lol." No doubt. The photo shoot took place in Antarctica. "Took us two months to thaw out," she said in another tweet.

The issue hits newsstands Tuesday, and Kate and nine other models will be appear tonight (Monday) on Letterman to promote it.
