Kendall Jenner is definitely announcing her adulthood!

The 18 year-old has posted a raunchy photograph 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!"

The revealing black and white pic shows the reality star intensely staring into the camera while sporting a wet head of hair that flows in front of her face.

The key feature..her breasts are exposed as she wears a see through black mesh top with no bra, clearing showing Jenner's nipples.

The older Kardashian sisters will most certainly be used to the millions of haters that scroll the internet, but this may be new to the younger Jenner, and as the hatred poured in, her big sister, Khloe Kardashian, was there for back up.

"Gorgeous @KendallJenner!!! High fashion! Model your booty off and show them how its done!!! Major Model Moment!," she tweeted before defending her lil sis, "I love seeing all of these haters comments. Naomi, Kate, Cindy.... All fabulous models.... Models and photographers take beautiful (1)...Artistic images. And I don't hear you birds chirp then. Sit down and enjoy the view! #SorryNotSorry."

Another preview shot just showed how revealing the shoot will be, Kendall shard a photo of her looking at some of the shots while wearing a pair of very small black pants that nearly exposed her butt.

The caption accompanied the photo read, "behind the scenes today.. literally lol @NomadRJ ."

Apart from the haters, there will be a lot of people (mainly males) looking forward to seeing the final product!
