Without giving too much away, in the episode "Mr. Schuster (Matthew Morrison) teaches the glee club a valuable lesson about self-acceptance and embracing what makes you unique through the music of Lady Gaga," according to press notes. "Meanwhile, Lauren Zizes (Ashley Fink) and Quinn Fabray (Dianna Agron) go toe-to-toe for the prom queen crown, Ms. Pillsbury (Jayma Mays) confronts her obsessive issues, Rachel Berry (Lea Michele) struggles with a life-altering decision and Santana Lopez (Naya Rivera) has something up her sleeve that could permanently alter the glee club dynamic."

Besides the highly anticipated cover of "Born this Way," the Gleeks also rocked out to some classic show tunes, including a mash-up of "I Feel Pretty" from West Side Story and "Unpretty," by TLC, as well as the song "As if We Never Said Goodbye" from Sunset Boulevard.

Also, catch Santana's famous line of the night, "The only straight I am is straight up b*tch." Well, we already knew that, didn't we?
