Justin Bieber 'Flaunts' His Calvin Klein Underwear Next to a Naked Statue in Stripped Down New Ads

Calvin Klein is "back in bed" with Justin Bieber.

The underwear brand is continuing its partnership with the 21-year-old "Sorry" singer with a pair of provocative new photos of the singer stripped down to his boxer briefs.

"I flaunt in #mycalvins," Justin captioned one snap of himself posing beside a naked statue.

Meanwhile, Calvin Klein shared a sleepy photo of the pop star (with his hand, well... you know, there), writing, "Back in bed with @justinbieber. Introducing the Spring 2016 Calvin Klein global advertising campaign."

Justin's professional relationship with the brand began last January, when the singer was featured in several shirtless ad spots as "the new face of Calvin Klein."

The steamy photos attracted lots of attention across the Internet, and ultimately became the subject of spoofs from Kate McKinnon on Saturday Night Live (her Bieber impression is perfection), "Wrecking Ball" singer Miley Cyrus, and even Justin himself, who spoofed the ads to promote his Comedy Central roast.

Despite all the fun and attention, Justin has stayed true to his Calvins, even sharing a photo of his wet, white undies while vacationing in Iceland.
