Looking for the name of a movie - main character doesn't realize he's dating a porn star

So trying to remember the name of the movie - probably 10 years old or more. One of the main characters doesn't realize he's dating a porn star.

One of the scenes I remember was he's with his girlfriend, they're meeting the priest who's going to marry them at a restaurant, and the priest looks at her and says "Have we met before?" and she says like "Oh ... ummmm no." Priest says "You look so familiar." .. At this point two other guys in the restaurant walk up and say "Oh my, it's so and so the porn star!" and the priest just turns beet red....

Does this ring a bell? LOL 
I swore the actor was Michael Rapaport  but I don't see anything in his IMDB history that rings a bell for the movie.
