Kate Upton: 'Why I haven't posed nude yet'

She's been topless, body-painted, floated in zero gravity and just about anything else you can imagine, but supermodel Kate Upton is yet to pose completely nude on a shoot.

"For me those photos are art. Your body is art, your body is beautiful, and to be photographed in that way is amazing and it’s received in a very positive way," the 22-year-old told Details magazine.

Clearly she's not against the idea of nudity, she's just worried about what you will think of her!

"With social media and the internet and not so great blogs and the attention like that, I don’t think that my pictures would be received in the way that I’d want them to be received. That’s why I’ve stayed away from them," the blonde bombshell revealed, without, well revealing anything.

When compared to models like Kate Moss, Naomi Campbell and Lara Stone, who have all stripped off in the name of art, Kate maintains that it's public perception that keeps her covered up.

"I really appreciate those photos and I think those women are beautiful, but I think social media and the internet has prevented me from putting myself out there like that."

The Sports Illustrated model has gone to some extreme lengths to nail a shot in the past. Check out some of our favourite Kate Upton moments above and below.
