Calvin Klein Underwear Spring 2015

Calvin Klein Underwear Spring 2015 is the fashion brand's high-profile ad campaign that put Justin Bieber front and center in nothing but his briefs. The pop star strips down to almost naked, showing off his physique in the kind of shirtless, skin-heavy footage that had fans hitting replay for weeks. The 1 scene collected here captures Bieber at his most exposed, all abs and attitude for the camera.
