The Biebers just made their fashion campaign debut â€” and it has us like baby, baby…. WHOA!

Justin Bieber and Hailey Baldwin stripped down to their Calvins for a campaign celebrating the 50th anniversary of iconic American label Calvin Klein. They also shared a steamy make-out session in the “anthem video” (above) created for the brand’s birthday.

In the sexy ads, the couple, who just celebrated their second wedding in South Carolina on Monday, models new underwear pieces from the CK50 anniversary collection, a limited-edition capsule of intimates and athleisure styles featuring a special CK50 logo.

The campaign, photographed by Glen Luchford, also stars A$AP Rocky, Kendall Jenner, Troye Sivan, Liu Wen, Parker Van Noord and Rebecca Leigh Longendyke.

“The campaign captures the rebellious spirit that has shaped the brand over the last 50 years,” the brand shares in a statement.

Along with the images, Hailey and Justin star in the celebratory video spot which takes viewers through the decades over the past 50 years.

The clip begins with the newlyweds sitting on a vintage couch watching the 1969 Apollo 11 rocket take off into space – marking the first time American astronauts landed on the moon.
