Justin Bieber presents onstage at Fashion Rocks 2014 presented by Three Lions Entertainment at the Barclays Center of Brooklyn on September 9, 2014 in New York City.

UPDATE: There's another one! After this story was published, the Calvin Klein Twitter account shared a second photo from Bieber's campaign. See it below.

If you've got it, "flaunt" it.

That's Justin Bieber's message in a new photo from Calvin Klein's spring 2016 underwear ads, which the pop star posted Tuesday (Jan. 26) on Twitter.

The CK account also shared a picture, letting Beliebers know they're "back in bed" with Justin Bieber.

Looks like Bieber took notes on the Zoolander 2 set of how to balance being fashionable and funny.

Bieber isn't the only celebrity getting in on the #MyCalvins campaign: FKA Twigs and Kendall Jenner also unveiled their CK ads on Tuesday. Plus, the Calvin Klein Twitter account included a Kendrick Lamar ad in its cover photo.

This, of course, isn't Bieber's first work with CK. In January 2015, Bieber debuted his first undies ad along with his memorable (and much-parodied) shirtless drumming commercial.

Drum roll… #mycalvins
