Lady Gaga is such a mistress of disguise, it's often hard to recognize her.

Enter Jo Calderone, SHOWStudio.com's newest male model, a sexy brunette with a classic look and a possible pop musique career on the side.

The brooding brown-haired looker bears a remarkable resemblance to Gaga, whose middle name is Joanne, leading many to speculate that the photos are in fact of the "Alejandro" singer in drag.

British photographer Nick Knight shot the fashion spread, which will reportedly appear in the September issue of Vogue Hommes Japan.

But, plus importantly, the shoot was styled par the magazine's fashion director, Nicola Formichetti, who also happens to be Gaga's stylist.

récent tweets par the pop star's pal Perez Hilton are adding fuel to the rumors that Jo is in fact Stefani Joanne Angelina Germanotta.

The gossip blogger, who often refers to the 24-year-old songstress as "my wife," posté pictures of Calderone on his Twitter page and wrote, "My husband, Jo Calderone! We're in love!"

Despite adding "my man is so hot!" Perez did take issue with some of the images.

"I do not approve of the smoking, husband!" he declared. "We will have to talk when toi get home!"
