Sports Illustrated Swimsuit Shocker! Kate Upton Sheds Bikini Top on Leaked Cover

Kate does SI ... again.Kate Upton made such a splash last year on the cover of the Sports Illustrated Swimsuit Edition, the magazine has apparently asked her back for a second round.

But this time, she’s not wearing a bikini top!

Instead, the curvy 20-year-old is oddly “bundled up” in a white parka, which of course is paired with white bikini bottoms in the purported cover photo, which leaked on Friday … three days before it was to be officially unveiled. But Upton fans shouldn’t worry: the jacket is unzipped, therefore her cleavage is still on full display.

Also strange about the cover shot? Upton is set against a snowy Antarctic backdrop – with the cover line “Kate Upton Goes Polar Bare” – instead of the usual beach scene. What gives?!

Kate's 2012 cover.

Last year, Upton had eyeballs bulging thanks to her teeny-tiny red string bikini. And the defining moment certainly bolstered her career. In the past 12 months alone, she has scored endorsement deals with 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.”

The Florida native is the ninth model to grace the SI cover twice. Only four others, including Kathy Ireland, have been on it three times. The top honor goes to Elle Mcpherson, who had five covers, including the best-seller from 1989.
