'Glee' does One Direction - Listen to 'Prom-a-saurus' songs here
Lea Michele takes the first verse on Fergie's "Big Girls Don't Cry," which will presumably feature Rachel tackling her disastrous NYADA audition before the rest of the gang joins in too. The gang also does another emotional ballad when Dianna Agron and Naya Rivera duet on "Take My Breath Away."
Things get a little more fun when Heather Morris does another Ke$ha tune quite well, and "Dinosaur" also suits the prom theme to a T (-Rex...get it?). Rivera takes the lead on Selena Gomez's "Love You Like a Love Song," while the guys of New Directions get their One Direction on with "What Makes You Beautiful."
