Kendall Jenner and other Calvin Klein models were bringing "The Original Sexy" back with their new underwear shots for the company's new campaign.

As reported by E! Online, the model and reality star had several sizzling shots with her wearing just a bra and another being topless and in just a thong. "Her long tousled locks and hardly-there makeup," according to the source cited above, made the shot even more "mesmerizing."

The same shots that many internet surfers went crazy about have been posted earlier by the young model to tease her fans.

"My new @CalvinKlein underwear," she captioned on a picture of her in just her bra that she posted on Instagram.

"Little tease at the new @CalvinKlein underwear," she wrote on another picture with her topless and only wearing a thong.

The 19-year-old seemingly looked confident in her shots and she admitted she has always been comfortable in campaigns like these.

""It was super fun," Kendall Jenner told Women's Wear Daily about her Calvin Klein underwear model gig. "Every girl loves posing in her underwear. It's always fun to do that."

The "Keeping Up With The Kardashian" star even admitted she loved what she was wearing for the shoot.

"[It's] definitely something I would wear," she exclaimed.

More campaigns for the Calvin Klein line are underway for fall, including the CK Magnetic, but Jenner was mum if she was going to be part of it as well.

"You'll have to wait and see," she said. "You have to keep some things secret."

Harpers Bazaar mentioned that "The Original Sexy" shots were taken by Mikael Jansson and was shot in New York.

According to the Calvin Klein's Chief Marketing Officer Melisa Goldie, the campaign in black-and-white was a move to reclaim the brand's signature sex appeal.

"Calvin Klein originated sexy and we're going to reclaim, re-imagine and re-image it," Goldie said as quoted by Harpers Bazaar.

"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," she said about Kendall Jenner's Calvin Klein campaign along with fellow model Joan Smalls, Isabeli Fontana and Edita Vilkeviciute.
