Kendall Jenner models Calvin Klein underwear a la Marky Mark

Kendall Jenner took to Instagram Friday to share a picture of herself in "her Calvins." "Morning! just going to hang out in #MyCalvins alllll day! ... thank you @calvinklein for my little gifts," the 18-year-old model captioned a picture of herself in which she shows off her new pair of Calvin Klein undies in a shot reminiscent of Mark Wahlberg and Kate Moss's Calvin Klein ads from the 90s. Jenner has been modeling full time since the beginning of the year. Thus far, the reality star has modeled bra-less for Marc Jacobs, in snakeskin garments for Givenchy and at a grocery-store runway for Chanel.
