That's what I think is so interesting about her. She's not your normal wannabe - she seems really in conflict between being a typical BB contestant (screeching and screaming, jumping in the pool at all hours etc) and being a good role model for her daughter (which, as a BB fan before she went in the house, she'll know that most people will see this as being 'boring').
I find it quite refreshing when a contestant won't shed all dignity in order to be on a TV show. It's one of the reasons I like Rachel as well (well, that and the fact they're both gorgeous! I'm a sucker for sultry brunettes!)
