Kate Upton's sexy 'Sports Illustrated' cover leaked

Kate Upton stuns on the cover of Sports Illustrated for the second time, this time donning a tiny white bikini in negative-degree weather.

New York Post reports that the voluptuous beauty graces the “Swimsuit 2013” edition, which hits the stands Feb. 12.

What’s more, the sexy cover was leaked and quickly circulated, showing 20-year-old Upton in a winter coat, bikini bottoms and nothing else.

According to TMZ, the photographs of the model during the shoot in Antarctica were previously published in December. One of the photos TMZ showed off was actually the one chosen for the cover.

Additionally, TMZ notes that during the photo shoot temperatures dropped down to 35 below zero, but Upton remained a pro in the frigid cold, wearing next to nothing.

The cover had circulated all over Twitter before the magazine finally debuted the cover two hours ago. The official debut has been retweeted over 1,800 times:
