#TroyAve’s going from hero to zero ... ‘cause it turns out he did NOT stand up to an armed robber — instead, he and his buddy staged a sh—tout for social media clout. Here’s the deal ... Troy’s pal, chef #GeoffCole posted a wild video Tuesday purportedly showing a g-nman sneaking up on both of them outside Geoff’s #SanDiego area home, only to have Troy whip out his own handgun and fire on the supposed assailant. Well, sources who’ve been in direct contact with the bogus bad boys have confirmed the whole scene was fake. No one actually attempted to rob Geoff, and we’re told Troy did not actually fire any live rounds. Via tmz_tv • highimheath
