The singer stayed in character throughout the duration of the ceremony at Los Angeles' Nokia Theatre on Sunday and also remained true to her role while rehearsing for the show.
VMAs executive producer Dave Sirulnick told MTV: "She showed up as Joe, rehearsed as Joe. If you said 'GaGa', she wouldn't respond.
"After rehearsals, she comes over, she says to me, 'It's nice to meet you', and I say to her, 'I know your friend GaGa', and she says, 'That GaGa, what a bitch!' She did not break character once.
"She walks in backstage and, in front of a whole bunch of people, went into the men's room."
Lady GaGa won two awards at the ceremony including 'Best Female Video' and 'Best Video With A Message'. Source
