Here's my take on her, based on what I've seen so far...
She's not particularly bright, but I think is probably quite a nice and sweet person. For example, in the parlour on her birthday she asked the other girls what
they wanted to do, happy to share her gifts. In choosing who to take to the parlour, after picking Tully she left the other spot open for a volunteer, offering the treat to whoever really wanted to do their hair. Even though she wasn't one of the ones causing the breakfast issues yesterday, she was sensitive enough to apologize on Tim and Heidi's behalf - and perceptive enough to suggest that they may not be realising how much the eviction was affecting them - but also recognising that while that might be the reason, it wasn't an excuse.
Looking at the videos and reading the updates, she doesn't appear to be involved in any of the bitch sessions or skirmishes (possibly because she's too busy sunbaking?) - and seems to make an effort to talk to all housemates. In some ways I see quite a level of maturity in her observations and thoughts - possibly due to her life experiences (independence and travel at an early age), and the fact that she recognised that the modelling life isn't actually the type of life she wants, and has changed her lifestyle accordingly, also shows some maturity and sense of being down to earth and in tune with her sense of self. I tend to agree that she may not know what she wants in regards to the boys, but she did say to Sharon that she found she was starting to look for guys that are not like her ex - so she may well be open to sampling whatever is on offer.
Looks-wise - to me she is just average (great figure though), so I think some of what is drawing people to her must come from within as well.
In terms of Drew, I did think that they were great together - and definite chemistry - but watching now I can see a divergence in the paths that each is taking in the house. Drew seems to be contracting his circle to Tim and Heidi (which could be dangerous for him as I don't think they are too popular with other housemates), while Jade seems to be moving beyond just hanging out with the HW HMs.
I don't expect that others will agree - but I am happy to agree to disagree
