Calvin Klein’s new intimate Spring ’16 campaign features an array of different celebrities, from pop-star Justin Bieber to rap prodigy Joey Bada$$, ‘Kardashian’ member Kendall Jenner, Kendrick Lamar and many more. The main theme of the campaign is “I___in #mycalvins” with each star admitting what they do in their Calvin Klein underwear. We’ve already seen a series of images shared via social media and some of the celebs have been combined IRL (kind of) in a campaign video—so you get a very personal look at what some of your favourite famous people really get up to in their Calvins.
