Does he actually represent her or does he just claim to?  Has anyone seen her through him?

If she is available and he does rep her, then it's likely others do too.

One word of caution about comments on twitter: many of the stars (including non porn stars) don't handle the social media themselves - they hire an assistant to do it.  So, just because "Eva Lovia" on twitter says that she doesn't escort it doesn't mean that is her posting.  It could just be an assistant.

I remember some years ago how I found this out.  I had contacted Jacky Joy, who I'd seen several times in the past, through her email.  I didn't know that Jacky now had an assistant handling her email and social media accounts.  Whoever it was adamantly insisted that she was Jacky Joy, that she never escorted, and she'd never been to my home.  When I saw Jacky at the next Exxxotica, I asked her about "her" emails and got the full story on how she hired an assistant who knew nothing about the escorting side of things.  Jacky then gave me her private contact info so I wouldn't have to talk to the assistant again.

The flip-side is also true.  Just because there's an ad on some site claiming a porn star escorts, doesn't mean it's true either.  There are lots of disreputable companies that will claim they rep particular stars and when you call them, you find out that star is not available (some excuse is given) but they can arrange for you to meet "someone just as hot" or "someone just as nice" or whatever.  The old "bait and switch" technique is rampant in this hobby.  That's a good reason to stick with well-known and well-reviewed agencies.  

Anyway, the point of all this is: don't believe everything you read on the Internet, especially Twitter, Facebook, Instagram, etc.

We did book for Eva and we had multiple people meet with her. Feedback was very good but she didn't want reviews written. She is no longer available through us and that's all I have to say about that
