It's a man's world for Lady Gaga.
In an upcoming issue of Vogue Hommes Japan, a model appears in a black tuxedo jacket and unbuttoned dress shirt.
Though the person is identified as "Jo Calderone," fans are buzzing that it is actually Lady Gaga in drag.
Adding to the speculation? Gaga's stylist Nicola Formichetti serves as the magazine's fashion director.
The "Alejandro" singer, 24, probably doesn't mind all the gender-bending buzz.
In February, she addressed rumors that she was a hermaphrodite in Britain's Q magazine: "We all know that one of the biggest talking points of the year...so why not give them what they want?”
