ICYMI: Justin Bieber Bared His Butt Again

Bieber's back at it again. Geddit? Teen pop sensation Justin Bieber bared it all another time in a recent Instagram post, revealing his back side (as opposed to his suprisingly-OK flip side).

Bieber's been camping it up with the CEO of the Shots camcorder app, John Shahidi, who snapped this lovely pic. At least they seem to enjoy being out in the wilderness together.

All we can say is that it is a beautiful shot --and the ass isn't bad, either. We're feeling a real Brokeback moment, here.
