This is a little off the main subject of "your favorite porn star," but many mainstream porn stars who currently escort can be found here:
www.bodymiracle.com
For example, Sophie Dee is one of my current favorites. She goes for $1800/hr.
And yes, Teri Weigel and Tracy Adams can both be found on this site.
www.eros-la.com also has a section specifically for "XXX Stars" which currently lists 44 lovelies. Rachel Love, another of my former favs, currently goes for $600/hr on that site.
I suppose any porn star with her own website will escort, but you have to be a paid member to find out. I didn't know that Lisa Sparxxx escorts in her home town of Nashville (and travels to do gangbangs) until I bought a membership to her website.
