Looks fishy to me, she was a popular trans porn star 10-12 years ago. I don't recall her ever actually escorting and the bottom, cut n paste link below, was from TER 10 years ago.  

I've seen her pictures in various escort ads in Chicago and other cities. The times I looked into them then I never found multiple escort ads or any reviews associated to the listed number. It's the same now, only the one ad associated with the number. Other things that are odd; the pictures and clips in the one add could have been taken from her Twitter account, top link below. The middle link below shows a different whatsapp # than the 401 number, does she have 2 phones?  Whatsapp is usually your phone number +1 for USA. I believe she's a Texas girl from Mexico but if you, but if you google the whatsapp # number it pulls up Boston. She's very hot, but I would walk away, too many unknowns...
