Kate Upton on ‘Sports Illustrated’ Swimsuit Issue Cover for Second Year

This wasn't supposed to be released until tonight (2/11) on the Late Show with David Letterman but we've got the inside scoop for you!

If you missed 20-year-old "It Girl" model Kate Upton starring in the Mercedes-Benz Super Bowl commercial, here she is on the cover of Sports Illustrated's Swimsuit Issue for the second year in a row!

According to our sources a fashion blogger spoiled the original release plans by breaking the news Friday tweeting, "POLAR BARE: @KateUpton in Antarctica is your 2013 SI Swimsuit Cover Model!" along with this cover photo showing the buxom Upton wearing white bikini bottoms with an open white fur-trimmed jacket and nothing underneath it.

Kated tweeted, "I look... Cold lol. Took us 2 months to thaw out."
