Just wondering how you know she is in town? Is there some sort AVN or other porn star convention or event? Did she post an ad someplace (which place?)?

If she is making a personal appearance someplace, be there and put your eyeballs on the real thing.  (If you like what you see and can make an appointment, then you can put your other balls on the real thing.)
.
If there's an ad, maybe, "I saw your ad but I was hoping there would be some recent pics." "... your pics didn't get posted with the ad."  
.
Depending on her personality, "What are you trying to hide?" could work ... to get you hung up upon.
