I was willing to give Sarah the benefit of the doubt, given that I haven't seen her and can't personally say if that's a fake photo. But she has another photo up today that 1) doesn't look anything like the person in the first photo, and 2) is obviously fake... the model is just too hot, the photography way too professional.... looks like it was ripped off from a modeling magazine.
Having said that: could it be her? Maybe, I haven't seen her in person. My guess: absolutely not.
