Justin Bieber's Pants Get Saggy In Singapore & He Almost Moons The Crowd!

Justin Bieber‘s been known to rock poopy pants before!

You know, where his harem-style bottoms are placed so low on his waist, it looks like he took a big poo-poo in there!

LOLz!

Justin’s concert attire was slung especially low in Singapore today, where he almost flashed his bitty-bitty-bum-bum to an entire audience of screaming pre-teens!

Fans were outraged that lil’ Bieb’s pantalones defied gravity, staying right below his butt without shimming to the ground!

Fortunately, Bieberoni’s ASSets weren’t overly exposed, but the potential of a full moon came way to close for comfort.

Ch-ch-check out a vid of Justin’s pants holding on for dear life…AFTER THE JUMP!!!
