Kendall Jenner has proven she's all grown up weeks after her 18th birthday. She shared a very revealing modeling photo on her Instagram with the caption, "sneak peak of today's shoot with the amazing @nomadrj ... can't wait for you guys to see the rest of the photos!"

We now wonder what else is there to see if this photo is just a sneak peak. Jenner was photographed by Australian Russell James, who regularly shoots scantily clad women for Victoria's Secret lingerie and swimsuit catalogue campaigns.

The young model has her eyebrow raised in a black and white photo, staring into the camera with wet hair and exposed breasts underneath a braless see-through black mesh shirt. She also shared a photo from behind the scenes, flaunting a sexy backside while she checks some of her pictures.

While her picture received some hate on the Internet, her big sister Khloe Kardashian Odom came to her defense on Twitter, saying "Gorgeous @KendallJenner!!! High fashion! Model your booty off and show them how it's done!!! Major Model Moment!"

She added, "I love seeing all of these haters comments. Naomi, Kate, Cindy.... All fabulous models.... Models and photographers take beautiful, artistic images. And I don't hear you birds chirp then. Sit down and enjoy the view! #SorryNotSorry."

The photos came out a day after Jenner and her half-sister Kim Kardashian attended the Alta Moda By Mario Testino photographic exhibition, where Kim was dressed exposing her nude bra and bosom underneath a likewise daring sheer cream top.

What would her protective father, Olympian Bruce Jenner, say about her decision to bare her breasts in front of the camera. Mr. Jenner warned photographers that his daughter won't be doing any nudes when he and Kendall attended his gallery opening in Los Angeles, in which Kendall starred months ago.

Kendall doesn't really have to show off her private assets to get attention. She was completely covered up for the New York weather with her cozy white seater, simple makeup and soft brunette curls to one side. The photo showed an uncanny resemblance to her big sister, Kim Kardashian.
