Justin Bieber Flashing his Black Underwear

Earlier this week, we finally saw what Justin Bieber was hiding underneath his pants, and those were his boxer briefs. But days before we ever saw Bieber in his skivvies, he was photographed leaving his girlfriend Selena Gomez's concert. As Justin was running away from crazy fans, his pants seemed to be falling down  (as always), which revealed the 17-year-old singer's black underwear.

Justin Bieber Flashes his Undies at the CMT Awards

Just because Justin Bieber is one of the most famous teens in the world, doesn't mean he can't dress like a normal teen. Like most teens nowadays, they wear their pants (loose or tight) down a little bit where you can see their underwear.

Justin attended the 2011 CMT Music Awards last night in Nashville, TN. When Justin stood up from his seat to receive his award with Rascal Flatts, he flashed his gray underwear with his pants below his ass!
