I see that this conversation can easily head in the wrong direction. Cory Chase may very well be a very nice and cool person. I don't know about any of that jazz.
I did, however, get curious and I looked into all of this a bit more.
Her frame could just be very masculine and I could be wrong. I don't mind being wrong, in this case it means, I learned something new.
Look at her broad shoulders (from her official FB page):
That is not muscletone alone, that is her also her skeletal structure. Women generally have a 2.5:1 shoulder to head size ratio, while men have a 3:1 (and above) shoulder to head ratio. I know the ankle somewhat "betrays" her, but the square shoulders (which she has in every picture) are also a prominent feature amoung the male population. Women generally have slanted shoulders.
Another picture I found from the shoot (google'd):
Shows a tree trunk neck, rather than a slim slightly incurve neck.
Female vs Male Neck:
None of this is definitive. Dispelling any doubt, do you have any picture of her arching her back? Women show a relatively sharp ankle (like an extra bend) in their spine when arching, as to elivate the weight destribution of their back in pregnancy (a bent they also have when they are not pregnant ofc.). This is something men definitely doesn't have. The adams apple can be "shaved", bones "restructured". The spine is another thing altogether.
