I won't knock her for spending her hard earned money as she wishes.
But you are right, she is not the approachable, low maintenance person that people think she is. Her ex roommate did an interview a few years back, talked about how JA was social climbing and turned her back on anyone who wasn't famous. And she was neurotically obsessed with being thin, encouraging her roommate to take drastic measures to lose weight so she could fit in.
I've had a few friends move to Hollywood and changed completely once they had a bit of success, so I know her type very well.
