Justin Bieber loves his drop-crotch pants - he wears them all the time and are a staple in his concert wardrobe. But sometimes he wears them a little low - a little too low. 

During his recent show in Jacksonville, FL, the Bieb rocked his signature pants on stage, a la red leather. He wore the pants low to begin with, but by the end of his performance of “Boyfriend” and “Baby” they ended up literally below his Bieber-butt!

Are these magical pants that defy gravity?! How do they stay up when he dances?!?! Are they attached to his underwear somehow???
