Is Hannah Montana a selfish person?

Miley Cyrus is a good role model at times but she is also a bad role model at times.. She dresses like any normal 18 year old would but that's just it she is not any normal 18 year old she is a famous person who a bunch of people look up to. but she has gone through alot so i do give her space of her own and i don't hate on her... p.s her brother trace is sexy
