I have worked with one of the Babestation ladies in a vanilla and unrelated job (BEFORE she was on Babestation). Was mildly surprised when she turned up on there and then also appeared on AW a short while later.
Its one of those questions most wont want to answer as if they say yes on a forum you can bet your arse there will be one person who cant leave it alone and will start PMing non stop trying to find out who it was. Even without naming names its still not very discreet to say yes. If the famous person reads it you can bet your arse you would never see them again and wont ever see anyone else who is in the same situation
