Exclusive: With all of its returning cast set to return and production officially underway, Universal has found a fresh face to join the “American Pie” gang.

Katrina Bowden is on board to round out the cast of “American Reunion,” the latest edition in the “American Pie” series.

Jason Biggs, Seann William Scott, Alyson Hannigan, Thomas Ian Nicholas, Chris Klein, Eugene Levy, Tara Reid, Eddie Kaye Thomas, Jennifer Coolidge and Mena Suvari are all set to return with Jon Hurwitz and Hayden Schlossberg writing and directing.

In this latest installment, all the American Pie characters we met a little more than a decade ago are returning to East Great Falls for their high-school reunion. In one long-overdue weekend, they will discover what has changed, who hasn’t and that time and distance can’t break the bonds of friendship.

Bowden will play Klein’s girlfriend who is an L.A. party girl type.

Craig Perry, Chris Moore and Warren Zide are on to produce with Chris and Paul Weitz exec producing.

It marks the first time most cast members will appear together since “American Pie 2.”

Several thesps, including Reid and Klein, did not return for “American Wedding” and only Levy was on board for the direct-to-DVD installments that Universal released.

After most of the cast was finalized in March, securing Bowden was the final piece before starting production.

U execs are excited to reunite the cast after seeing the response to the latest installment of “Fast & the Furious” franchise, “Fast Five,” which brought back much of the original cast.

The “American Pie” franchise has grossed more than $700 million worldwide.

Bowden is best known for her role as Cerie on “30 Rock” and can also be seen next in “Piranha: 3DD.”

She is repped by ICM and Management 360.
