The cast of the 1999 teen comedy American Pie reunited on Entertainment Tonight for the movie's 20th anniversary, and this amazing photo was posted on Social Media of them all together. For the occasion, the reunion featured Hannigan (Michelle Flaherty), Jason Biggs (Jim Levenstein), Tara Reid (Vicky Lathum), Chris Klein (Chris "Oz" Ostreicher), Seann William Scott (Steve Stifler), Natasha Lyonne (Jessica), and Eddie Kaye Thomas (Paul Finch). It appears that the American Pie gang hasn't aged a day over the past twenty years.
