Kate Upton Nearly Nude! [WATCH VIDEO] Sports Illustrated Releases Footage Of The Model[PHOTOS] Looking HOT In Antarctica

Kate Upton Sports Illustrated footage has been released featuring the 21-year old model during the photoshoot in Antarctica.  Upton was seen in the freezing cold, but wearing just a skimpy bikini while the crew were all bundled up.

The video featured behind the scenes footage of the Kate Upton photo shoot for the cover of Sports Illustrated magazine released months ago.

Kate was playing with the penguins, which served as backdrop for her Sports Illustrated photoshoot. A series of hot images of Upton in her sexy bikini and then none at all, but only with a heavy jacket to cover her twins, have been the source of anguish for men.

Swimsuit editor, MJ Day, said how Kate pulled it off looking her best in the camera while freezing outside in the Antarctic.

"It could have had a blizzard. Kate could have had shivering fits you could not shoot around. (Instead) we had six days of perfect weather," MJ Day was quoted as telling CNN in February 2013.

In June,  Upton also grazed  the cover of Vogue.

One of the main topics of conversation Vogue had with Upton was her figure and her efforts to ignore those critical of her killer curves.

"The thing that they're rejecting I can't change," Upton said. "I can't change my bra size. They're natural. I can work out and I can stay healthy and motivated, but I can't change some things. I really just live my life."

She added, "I love my body. It's what God gave me! I feel confident with myself, and if that inspires other women to feel confident with their bodies, great."

Kate looks amazing and she's also a tough chick getting nearly nude in Arctic weather.  We'll be watching this models budding career closely.
