Mamma Mia and Mean Girls star Amanda Seyfried recently made an appearance at the Williamstown Theater Festival in Massachusetts and brought all of her sassiness.

And you guessed it! The two "Plastics" sprinkled the performance with as much Mean Girls references as possible. Try and see if you can spot 'em all. Check it out here:
