I always thought a porn star was someone who stars in the scene. Like if this was the script to a movie:
Secretary: Mr Johnson, you're new trainee is here to see you.
Mr Johnson: Send her in!
*trainee enters*
Mr Johnson: Now get over here and suck my dick bitch
Mr Johnson & the trainee would be the porn stars where as the secretary is just the adult film model. Well, that is assuming the secretary doesnt turn it into a wild threesome.. then she'd be a star too in my books.
