Calvin Klein's New, Racy Ad Campaign Sparks Controversy

Sexy underwear brand Calvin Klein coming under fire for new ad campaign.

The brand’s spring 2016 promotion uses an assortment of social media ads asking users to fill in the blank: “"I _______ in my Calvins.”

In one photo causing a stir, Kristin, 23, poses in a skirt above the camera, while the caption reads “I flash in #mycalvins," along with #takeapeek.

People are taking to social media responding to the ad, calling the picture “a new low” and “disgusting" and "unnecessary.”

“They’re trying to connect with millennials, but the ad isn’t about the underwear; it’s more about the voyeur,” Adweek staff writer Kristina Monllos told ABC News. “Something about that feels weird and gross and crass in a way that makes people uncomfortable.”

Another series of photos show Jenner posing provocatively with half a grapefruit and a caption reading “I eat in #mycalvins.”

Calvin Klein did not reply to ABC News' request for comment.
