WATCH: Broadway stars Lea Michele and Jonathan Groff take over a school talent show

Tony Award winner Jonathan Groff and Emmy Award nominee Lea Michele step into PS 57 in New York City to transform a classroom into a full blown showbiz bootcamp.

This episode of Celebrity Substitute is a full-throttle masterclass in star power, stage presence, and surviving the spotlight.

Reuniting years after their iconic days on Glee, these Broadway besties bring their choir-room chemistry straight to the classroom.

Inspired by the musical Gypsy, these Broadway besties kick things off with a legendary lesson from showbiz history: “ya gotta have a gimmick.” From violin solos to a Hamilton inspired performance, the students learn that standing out is half the battle.
