We knew that at the VMAs, Lady Gaga was so committed to playing her male alter ego Jo Calderone that she never broke character, even when facing the press backstage. But it seems her performance went even deeper than that: A Gaga insider confirmed to Us Weekly that the singer wore a prosthetic penis to complete her get-up. (Or, if you prefer, "wore.") No one was more convinced than actor and Dancing With the Stars alum Ralph Macchio, who tweeted out a photo comparing Jo Calderone to his look from The Outsiders and noted, "Getting the urge to crash the dwts cast announcements tonight dressed in rib eye steaks and a blonde wig."
