Another American Reunion holdout has officially joined the cast. Sexy foreign exchange student Nadia, embodied by Shannon Elizabeth, will be returning to the hallowed halls of East Great Falls high school in this fourth installment of the popular theatrical arm of the American Pie franchise.

Shannon Elizabeth will once again play the Czech native who makes young pubescent boys ejaculate prematurely. Nadia will serve the storyline much in the same way that Christie Brinkley served the Vacation series, as an object of forbidden desire for the now married Jim (Jason Biggs). And she may just beg the age-old question, "Is prematurely ejaculating in your pants considered cheating when you haven't even touched the other person yet?"

Natasha Lyonne, who played rebel Jessica, and Chris Owen, who played nerd Chuck Sherman, are the last two holdouts, and there isn't any word as to why they haven't signed on at this time.

Shannon Elizabeth is set to start her part of filming next week in Atlanta, Georgia, where shooting is already under way.
