I should imagine Rex calls her "Princess" because her parents did. She has obviously been spoilt since she was little and got everything she wanted when she wanted. The think now of course, if Rex goes, which is what he wanted origianlly to get out and see her, he won't want to now cos she's in there. Even I am wanting her to have her damn suitcase now! Its quite warming to see how they really look without their beauty products, apart from Lisa of course! Did she go through the audition process??
