The first batch of official photos from "American Reunion" is here -- proving the boys are back and Stifler's mom is bustier than ever!

Universal has released seven brand new photos from the upcoming "American Pie" sequel, coming out 12 years after the original flick.

According to the official synopsis, the original cast returns to East Great Falls for their high-school reunion and "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."

Check out the photos to see Jason Biggs, Chris Klein, Alyson Hannigan, Seann William Scott, Eddie Kaye Thomas, Thomas Ian Nicholas, Tara Reid, Eugene Levy, Mena Suvari and, of course, Jennifer Coolidge in action.

The movie opens April 2012.
