its all an act, if you dont realise she is acting like this for attention, fame and money, your the one that is nuts.
tell any women she can be a millionaire by wearing weird scantily clad clothes and hanging about with star's and most of them will do it, have you not seen the playboy mansion?
she is after, fame, money and attention and it looks like she will do whatever she needs to do in order to achieve it.
i bet marilyn manson doesnt actually want to look like a complete idiot but he does it to suit his fans, lady gaga is just the male version of marilyn manson in a different genre of music.
can you not tell by the controversial name change? nobody liked her old name, now she's lady gaga, lady implies sexiness and gaga implies craziness, so she has took those two things to another level in order to get noticed and rich.
