Karlie Kloss poses nude for the first time in Vogue Italia, showing off her extremely tight and toned body that is both mesmerizing and disturbing at the same time.

Kloss, 19, gives new meaning to the term zero body fat. She is all muscle and skin in an 18-page spread, styled by fashion editor Carlyne Cerf de Dudzeele and shot by famed photographer Steven Meisel.

Kloss, who walked in the Victoria’s Secret Fashion Show for the first time last month, has talked often about her athletic lifestyle and dancer’s background.

But the feature, titled “Body by Kloss,” is crazy.

The 5’11” tall model looks almost like an alien with her long sinewy legs, tiny torso, long thin arms, wide eyes and sharp cheekbones.

Kloss’s waist is so small in one shot, Vogue Italia pulled it from its Web site over concerns it would be accused of photoshopping the image. But it’s likely all Karlie.

Kloss was born in Chicago and grew up in St. Louis. She studied ballet and still has a dancer’s body.

Today, she is one of the fastest rising models in the industry.

She’s ranked 3rd on the Top 50 Models Women List published by models.com, and Vogue Paris declared her one of the top 30 models of the 21st Century.

She signed with Elite Management in 2007 at just 15 and debuted in Teen Vogue’s August issue that year. She’s now represented by Next Management.

It’s almost like she was born catwalk-ready and has walked for such top designers as Oscar de la Renta, Carolina Herrera, Jason Wu and Marc Jacobs.

Vogue Italia editor Franca Sozzani says Kloss is the new “Body” in modeling.

Elle McPherson is the only other model to earn that accolade.
