Kendall Jenner continues to grab attention on Instagram with her latest post being in her underwear. But it isn't just any brand that she is flaunting, it's her Calvins!

According to E! News, this morning the model took to her account to post a photo of herself in some Calvin Klein attire channeling her inner Mark Wahlberg from his past ads with the company.

In the snapshot the 18-year-old model flashed a huge smile while sitting on a backyard lounge bed.

Kendall Jenner wore a pair of saggy jeans that hung off of her butt and showed off her white CK briefs. Up top, Harry Styles' ex-girlfriend only wore a white CK bra.

Attached to the hot photo was the caption, "morning! just going to hang out in #MyCalvins alllll day! ... thank you @calvinklein for my little gifts."

It looks like the "Keeping Up with the Kardashians" star wanted to have some fun after being ridiculously busy walking in the Chanel and Givenchy show during London Fashion Week.

Her big sister Kim Kardashian is especially proud of her as she praised the young model. North West's engaged mom explained, "She went and auditioned, and she just goes by the name of Kendall...She works her butt off.

"She just goes to casting after casting. I'm so proud of her that her Fashion Week was able to achieve all the shows she was able to walk in. She's living her dream and it's so inspiring to watch her."
