Who is jealous of Bella in twilight?

As in the book, Rosalie, is very beautiful and apparently no guy has ever not been attracted to her, so, when she met Edward she had a resentement towards the fact that he showed no interest in her whatsoever. And when Bella came along and Edward was in love with her, Rosalie flipped. Even though she is quite in love with Emmett and probably wouldent have been interested in Edward, she still resents the fact that he wasnt attracted to her. So, basically, Rosalie was jealous of Bella for getting Edward's attention so easily when she couldent.
