Apparently Gaga stayed so much in character as Jo Calderone, Gaga's greasy-haired, outspoken, on-again-off-again lover of Italian descent, that she caused security issues backstage at the popular music awards show because no one recognized her. Can you blame them? Gaga even went as far as to wear a prosthetic penis for her night in drag as Jo Calderone!
After Gaga's friend and former collab partner Beyonce made her big baby announcement on the VMA black carpet, Mother Monster couldn't wait to congratulate the mother-to-be, but security guards initially blocked her from visiting her pregnant pal!
An eyewitness source told UsMagazine.com, "She kept coming over to rub Beyonce's belly and say hello. And the security guards thought she was a guy at first and wouldn't let her back! It was really funny."
