Their dayjob involves a lot of fantasy and regularly humoring completely ridiculous "set up" scenarios. Suspension of utter disbelief is obviously something they get to exercise on a regular basis, so they've already got some of the key skills for roleplaying - and before you slag porn stars acting skills, consider some of your fellow roleplayers acting skills or utter lack therof.

Disclaimer: I used to game with a porn star (male, not female), and I still game with a former phone sex operator (again, male, not female). They're mostly just your average 50 point characters, PLUS enough bonus points to pay for Voice or Appearance ;)
