I thought they were real for the longest time, but I'm pretty sure fake now. She even posted a pic on twitter from only a year or so before she started modelling where she was totally flat. Hard to believe a woman can go from flat to GG in a year post-puberty naturally. We've all been impressed by great fakes from people like Sophie Reade, Ava Addams, Brandi Robbins, etc.
Also on her back they don't exactly go flat or to the sides like real ones.
