Justin Bieber has been working his butt off ... or should we say his abs? He and his trainer posed for a photo today on Instagram that will even make all the straight boys turn their heads. (I have witnesses to that.) Check out the Biebs as his body has turned into a jacked piece of artwork with killer abs.
... Someone get me some water and some ice cubes to cool down ... I think I caught Bieber Fever from these hot photos.
