do you know her personally? Cause honestly I'm pretty.. well, honest, and if any of my friends did that I'd flat out say "thats really creepy and not ok." And besides, those mostly look like they were done with a professional photographer in a photo shoot, and look like professional models. If her page doesn't say anywhere that she's a model I'd be suspicious.
And disclaimer: honestly I'm horrible at faces, they all LOOK like different people to me, different piercings etc, but I don't know for sure. I can never go with my instinct on these things cause I simply am horrible at remembering faces

But I KNOWWWW I've seen that picture before, damn you!
Also, I commend you for doing your research before calling her out.
