Justin Bieber apparently got so incensed while in the heat of "battle" with a woman at a gym in North Carolina on Tuesday (Jan. 22) that he mocked her workout routine, cussed at her and even spit in her water bottle. OMG, what's wrong with him? Does he have some type of roid-like rage when working out, as his testosterone and adrenaline build? Eh, not so fast. The Biebs camp steadfastly denies the woman's seemingly preposterous claims.
