This woman is cray cray! Amazingly talented…but cray cray! Gaga appeared as her “alter ego” Jo Calderone at the VMA’s on Sunday and according to reports, didn’t break character one time! Not backstage, not in the audience and most certainly not on stage (as well all saw.) Now new details on her act have arrived…and come to find out she took it so far as to have a fake penis under her clothes as well! Yikes!! Details after the jump.

The pop provocateur (real name: Stephanie Germanotta), 25, didn’t just wear men’s clothing (including Armani men’s underwear) and fake stubble in her “drag king” get-up: To complete the gender-bending transformation, Gaga wore a prosthetic penis, an insider confirms to Us Weekly.

The “You and I” singer stayed in character throughout the night at the Nokia Theater.

“I am from New Jersey,” Gaga as Jo told Us backstage. ” My family is from Palermo, Sicily and I am not a singer or a model or an actor or anything. I am just a guy.”
