Justin Bieber and his Calvins have called it a night.

The “Holy” crooner, 26, was spotted filming a music video over the weekend in downtown Los Angeles, where he was photographed wearing his white Calvin Klein briefs and nothing else.

Bieber — who stripped down for a new Calvin Klein campaign earlier this year — was also seen raising his arms and flashing a smile as he walked to what appeared to be his trailer.

Also on set, Bieber’s wife Hailey Baldwin, 23, who bundled up in a cozy robe and jeans.

On Saturday, a clothed Bieber sported cowboy threads for pal Kendall Jenner’s Halloween-themed birthday party, while Baldwin channeled Nurse Dolly from the Netflix series “Ratched.”
