Actually, I think it's prostethic, not photoshop. There's a video of her moving around in the bikini.
Also, she's done some other kind of internet-hoax stuff before; I don't have the article but google around and you'll see. I think she's a massage therapist in Florida or someplace like that, who must enjoy the attention.
Nevertheless - I'd still hit it. And take photos so I could pretend it was real...
