if you take a close look at he there are three thing.
1) the mole on the left side of her face
2) the mole on her right arm
3) the mole on her chest by the neck.
Some were airbrushed out but if you go back through amy's photos you can find examples of all three of the moles in the right places. Also, she clearly had a nose job. If you just look at the shape and proportions of her curves, boobs, and even her posing style, they are all identical. I'm pretty sure its her and if you take the time to go back I think you will see it.
Keep in mind that a nose job can really make a difference....
