Kendall Jenner loves hanging out in her Calvins. . . so much so that the 19-year-old model is now the new face of the underwear brand.

The high-fashion model is currently walking the runway for Chanel and Balmain in Paris for fashion week.

Jenner has been wearing Calvins for a long time and has posted the evidence of her love for the brand since last year when she uploaded pics to her Instagram account wearing the iconic briefs and bra.

The "KUWTK" reality star's social media account - with more than 20 million followers - mimics that of Justin Bieber. Bieber also posted selfies wearing Calvin Klein underwear, which then led to him becoming a spokesman for the brand.

Bieber's appearance in Calvin Klein ads with model Lara Stone garnered a lot of attention, and Calvin Klein instantaneously acquired 3.6 million Twitter followers after the first image was released, according to Page Six.

The pop singer's photos also raised eyebrows and had viewers wondering if his body (and his manhood) had been photoshopped or enhanced for the photo shoot.

Add the alluring Kendall to the mix, and who knows what will happen to Calvin's list of followers - photoshop or not.
