Second year in a row the sexy model was chosen as the cover girl for the annual Sports Illustrated swimsuit issue.
“It was freezing,” Upton, 20, told NBC’s morning TV show “Today” on Tuesday. “I’m from Florida, so it wasn’t easy for me.”
“When I came back, I was losing my hearing and eyesight. My body was shutting down because it was working so hard to keep me warm.”
The model was taken by surprise as she was the only model being whisked away to the far away continent for the photo shoot.
“I was very surprised by the news that that’s where my shoot was going to be located,’’ the SI model said further discussing the difficulties. She even joked on Twitter that when she got back it took two months to thaw out from frostbite.
“When I came back I was losing hearing and eyesight because my body was shutting down,” Upton continued. “It was working so hard to keep me warm. My mom’s in my ear going ‘I told you not to go there. It’s a bad idea!’”
However, the sexy blonde known for her incredible curves seems to be thrilled about such an unusual experience.
“It was an accomplishment just to get through the shoot…I didn’t even think about the possibility of being the cover until after I thawed out a bit!” the 20-year-old told People.
“But now it’s like, wow – I actually went down there and was able to accomplish that. I’m part of history, and it’s a great feeling (sic).”
It took three years to organize the photoshoot due to high costs and scheduling, marking it as the first-ever fashion shoot that has taken place in Antarctica.
“Everything about the picture is perfect,” SI editor MJ Day told People while backing up Upton’s remarks about how difficult it was.
“First of all, it’s cold, even though we were there in summer. The windchill was sub-zero – the elements are really working against you.”
“I knew that if I needed to bury someone in clothing, I needed her physique and curves to come through,” Day added.
“So to bring her was obvious: I knew I could put a one-piece on her and she wouldn’t look flat, she’d still look voluptuous and healthy and shapely and sexy.”
However, MJ Day revealed that Kate proved one more time that she is a true professional.
“She never complained. She’d just say, ‘Okay, let’s go do it again,’” praised Day. “I knew that if I needed to bury someone in clothing, I needed her physique and curves to come through.”
Upton’s now-infamous Canada Goose Chilliwack Bomber coat, combined with white Letarte by Lisa Cabrinha bottoms, was an afterthought.
“I figured, why not a coat?” Day says. “We threw it on, took maybe 100 frames, then moved on. Then that night, the photographer and I were looking at photos, and he said, ‘I don’t know, could this be it?’ It just had that energy.”
The only downside of the whole experience was the fact that the cover of the magazine leaked online on Friday, four days before it was supposed to be revealed.
“I didn’t get to tell Kate she was the cover, which was kind of sad,” Day says. “I wanted to see the look on her face when she found out.”
