It is possible to become friends with an adult actress, JCMSVOBODA is a good example of that (he has contact with an adult actress named Farrah), but it doesn't happen too often & I personally believe that it's best to let the actress initiate the private contact & not look for ways to contact the actress yourself.
The best thing you can do is look for a myspace and/or facebook page. If she speaks English, then she'll probably have one of those, but if she doesn't speak English, she probably won't have a profile page (or maybe a page on a Hungarian equivalent of the sites mentioned above) & assuming you don't speak Magyar, you won't be able to communicate with her.
