Spring Awakening Stars Lea Michele and Jonathan Groff Go 'Rolling in the Deep' on Glee

As Glee's Rachel Berry (Lea Michele) prepped a show-stopping number for McKinley High's prom, the young diva was confronted by a very unexpected visitor: her ex-boyfriend Jesse St. James! Jesse's return to the series marks a reunion for Michele and her former Spring Awakening co-star and real life best friend, Jonathan Groff. Given Rachel and Jesse's history together (Jessie was last seen on the series humiliating Rachel by breaking an egg over her head alongside members of a rival show choir), it's no surprise to see the duo share an emotionally charged duet of Adele's hit song "Rolling in the Deep." If seeing Michele and Groff back together again isn't enough Broadway for you, the Glee crew also tackled ABBA's iconic disco hit "Dancing Queen" (which is featured in Broadway's long-running hit Mamma Mia!) on the prom dance floor.
