It's the same girl, no question about it. As I have membership to met-art, I compared most of Gella/Jordan photos at max resolution looking for similarities (moles, birthmarks, etc). Photographers didn't make it easy as the Gella's photos appear to be heavily retouched, but I did find a few that are in the same places. Actually, the funniest similarity is a very tiny mole right next to her asshole.
