Mean Girls is ready to sing at Washington, D.C.'s National Theatre where the Broadway-bound musical will make its world premiere this fall. Casting was announced yesterday and musical theater fans have been promised a host of stage favorites to fill out the population at North Shore High School.

Kinky Boots star Taylor Louderman and Ashley Park (veteran of The King and I and Sunday in the Park With George) join the Plastics as head Mean Girl Regina George and her closest minion Gretchen Wieners. With any luck, Park will soon be leading a Julius Caesar-themed production number about the downfall of Regina with Louderman acting out the coup in a Roman dreamscape. But for now, we can watch the two duet to Lady Gaga's "Poker Face." It happened in 2013 — so basically during the Roman Empire.
