Why not point her out? How would she be able to identify you if any of us saw her?
If it were me and she was someone I was crushing on then I'd have a quiet word next time we met. Bit of conversation to suss out if she's got a BF, perhaps admit to an embarrassing crush on her, bit of a sob story about not finding a decent GF, considering a naughty massage because it's been so long. See how she reacts. If she takes the bait would see if she's up for dating or an arrangement (for less than her advertised hourly)
