Oh la la!

Justin Bieber and Kendall Jenner bare (almost) all in the new Calvin Klein underwear campaign, and while the supermodel looks stunning, we're more focused on The Biebs' package! He certainly has a handful down there!

"What do superstars, musicians, models, actors and artists do in #mycalvins? Find out in the Spring 2016 Calvin Klein global advertising campaign, featuring @justinbieber, @kendricklamar, @fkatwigs, @kendalljenner, @abbeylee, @fettywap1738, @teriyakipapi, @saskiadebrauw, @adwoaaboah, @joeybadass, @karate_katia, @princessnokia and more. Photographed by Tyrone Lebon," the brand captioned a promo video.

With some underwear ads, like David Beckham for H&M, it's obvious they're stuffing their packages, but we've seen JB's willy in those Bora Bora naked pix and that's definitely ALL him!
