Justin Bieber seems to have developed a rare but serious allergy to wearing pants. The pop star was caught stepping outside in Miami in just his underwear by the paparazzi on Monday (January 28). And this time, the photos can’t just be deleted off of his Instagram. We would chuck this wardrobe mishap up to shirtless Biebs having all of his energy focused the big countdown to his Believe Acoustic album (debuting Tuesday, January 29), except that it does appear that the “All Around The World” crooner is flashing his six-pack and tattoo collection at the cameras. It’s as if JB is reminding us of his new single status — as if we could for one second possibly forget.
