GaGa falls awkwardly between superficial sexpot and delusional dillettante, so it's not surprising for me to see her acting in such a confused manner. She either A) think she's doing it in the name of art, or B) making a radical statement or something like that.
That being said, the people at the game should know better, and just ignore her. I suspect a mental breakdwon in the coming years...I hope it inspires better music.
