Lady Gaga just won't stop toying around with those hermaphrodite rumors. Now, the ever-eccentric pop star appears in drag (?) for an upcoming issue of Vogue Hommes Japan. Perez Hilton and Gaga's stylist, Nicola Formichetti, teased the Twitterverse this morning with photos of a mysterious male model -- one that happens to have a strikingly familiar profile. Formichetti credits the model as "Jo Calderone," but he later linked out to a blog debating whether or not the mystery man is indeed Gaga. And that's good enough for us. So what do you think of Gaga, er, Jo's new look? Should she ditch the blonde forever? Check out another photo from the issue after the jump. >>
