I agree about the boobs LG.
I do think a lot of this specualtion has come about because of them.
She is very slim and does have quite a "boyish" figure e.g. not much of a difference between waist and hip measurements.
Man, woman, intersexed , whatever - Erin is doing a great job on Survivor so far.
She's has shown a good work ethic and seems to be anything but the airhead bimbo many people had her down as before the show started.
