She did a few years ago.  I don't know if she still does.  The last time I asked about it, I was told she was in a "serious relationship" with another actress (maybe Haven - I don't remember for sure) and had taken a break from escorting.  The only place I've seen her advertised is on Nici's web site but that doesn't mean anything since Nici post girl's she doesn't represent.

The best thing to do would be to email Brittany privately, and discreetly inquire...
