The “Stitches” singer got in his workout on Feb. 22, when he hit the trails at Los Angeles’ Runyon Canyon with his longtime doctor Jocelyne Miranda. For the occasion, Shawn—who recently traded his signature wavy hairstyle for a shorter buzzcut—went shirtless, opting for black hiking shorts and matching sneakers. Meanwhile, the chiropractor donned a black tank top, black leggings, white sneakers and oversized sunglasses.
