In the upcoming highly anticipated Sports Illustrated Swimsuit Edition, Kate Upton “polar bares all” on the cover! Everyone was so impressed with her cover last year, that she made the cover once again, but this time sheds her bikini top! They also set her up on an Antarctica background instead of the usual steamy beach scene! Upton received a lot of endorsement deals (Mercedes-Benz, Carl’s Jr., Guess, Sobe, and DirecTV, as well as a minor role as a nun in the Farrelly Brothers’ “The Three Stooges”) from her sizzling 2012 cover in the classic thin red thin bikini (pic below)! The model who became famous for messing up her lines on an intelligence section of the 2007 Miss Teen USA competition [Video] has boosted to celebrity behind her now 20-year old busty body! Check out the pics!
