If the girl is who I think it is, then it's quite possible that she has quit escorting or has possibly gone deep UTR because she was being stalked.

 I cannot post the article link here because it gives her real name and TER prohibits links to articles that include real names.  But, if you do a search, you can probably find it yourself.

Regardless, I'm sure if you ask around, especially at TLC, you'll probably find out if she is still available.
