Upton reportedly took a 10-day trip from Argentina to Antarctica from November 29 to December 9 to shoot the latest Sport Illustrated cover. TMZ posted
the photo shoot of the 20 year old model on top of a cruise ship, with floating glaziers, ice bergs and freezing ice water as background.
The model and former equestrian can be seen wearing a skimpy white bikini, with a white fur coat and white boots. In the TMZ post
, Upton can also be seen getting intimate and close with a giant Oreo cookie man, with the Sports Illustrated crew preparing for the photo shoot.
The appearance of the huge Oreo cookie in Sports Illustrated is reportedly in celebration of Oreo's 100th year anniversary in the United States. Upton's cold and frigid swimsuit edition strip down on the sports magazine can be seen in early 2013.
Upton is ranked as the fifth sexiest model in Models.com and ranked 3rd in Askmen's 2013 Top 99 women.
