Justin Bieber, Kendall Jenner strip down for ad campaign

Justin Bieber and Kendall Jenner have been tapped for Calvin Klein's 2016 spring global advertising campaign.
Both of them took to Instagram to share photographs of themselves in their Calvin Klein underwears, reported Ace Showbiz.
As the campaign particularly asks them what they do in their Calvin Klein underwears, Bieber, 21, answered, "I flaunt in #mycalvins."
His answer appeared as a tagline in an image he posted on the photo-sharing website. The photograph showed him shirtless flaunting his toned figure in black Calvin Klein boxers. He lifted up one of his arms and one of his legs. A white statue of a naked woman stood next to him.

Meanwhile, Jenner, 20, gave a flirty answer to the question from the campaign.
"I want to be with you in #mycalvins," she said.
