Chris Klein can't get enough American Pie.
The actor, 32, will reprise his role as Chris "Oz" Ostreicher in the upcoming film American Reunion, his rep confirms to Us Weekly.
Klein -- who successfully completed a 30-day alcohol addiction program last summer -- joins fellow American Pie alums Jason Biggs, Seann William Scott, Eugene Levy and Alyson Hannigan. Filming begins May 24.
The actor most recently guest-starred on the soon-to-premiere FX comedy Wilfred (starring Elijah Wood).
