Kendall Jenner took part in a steamy new photo shoot for the newest Calvin Klein Underwear Campaign. The supermodel stripped down to almost nothing, posing topless and flashing her full butt in a thong.

The 19-year-old model and reality star was photographed in a black mesh thong for the new ad, and she looks beyond incredible. The photos are for a series of new ads for the Fall 2015 collection, which will come out at the end of the month, according to People.

With her full-toned butt on display, and a nice touch of side boob, these may be some of her sexiest photos yet. She posted the photo to her Instagram with the caption, "Little tease at the new @CalvinKlein underwear #MyCalvins."

Another photo from the shoot, which she also posted, shows a more close-up shot of the beautiful brunette, and this time she's in a matching black lace bra. "New for @CalvinKelin underwear #MyCalvins," this caption read.

"It was super fun," Jenner told WWD about the photo-shoot. "Every girl loves posing in her underwear. It's always fun to do that."

There was one other photo that showed a full-frontal shot of Jenner posing in the matching black lingerie set for their "Original Sexy" campaign, according to Us Weekly. The flawless photos, which are all in black-and-white, were shot by fashion photographer Mikael Jansson.

"Calvin Klein originated sexy and we're going to reclaim, re-imagine and re-image it," Calvin Klein Chief Marketing Officer Melisa Goldie said in a statement. "We're bringing together a powerful mix of women from all over the world to celebrate our heritage as a leader in the intimates category."

This is Jenner's second global ad campaign with the brand. Her first set of photos, which were for Calvin Klein's "Denim Series," were released in March. At the time, she was featured on a few giant billboards in major cities across the country.

This also isn't Jenner's first time posing topless. She's been featured in similar topless shoots for Love Magazine and GQ, as well. Even her Instagram is filled with tons of racy, high-fashion photos. As a model who takes her shoots seriously, she continues to look amazing in every single photo she posts, no matter what she may or may not be wearing.
