The reality star alum shared the photo with followers early Friday, revealing he had run into the pop star at Post Malone's concert Thursday night in Los Angeles.
The pairing a stylishly unique one as Pratt was proudly sporting a tie-dye shirt embellished with "Pratt Daddy" on the front—a nickname for the star, who became a dad in October 2017 with longtime love Heidi Montag. As a very fitting accessory, the crystal aficionado also rocked one around his neck.
As for Biebs, the crooner was rocking his recent mustache and long blond hair held down by a bandana. He matched Pratt's vibrant shirt with a Hawaiian-style button down of his own.
