The American Pie gang is together again! The premiere of American Reunion was held last night at Grauman's Chinese Theatre and though the stars of the hilarious film franchise are all grown up, they proved they're just as silly as ever as they posed for photos on the red carpet.

The whole cast was in attendance -- including a very pregnant Alyson Hannigan, and Jason Biggs -- who, of course, posed with a pie.

Check out our awesome photo gallery of the event after the jump!
