GLEE Cover's One Directon's "What Makes You Beautiful"

We're on a bit of a GLEE high wondering how GLEE will wrap up as the season slowly comes to an end. Being that we're also on a One Direction high, this news is more than appropriate: tomorrow night, GLEE will be covering "What Makes You Beautiful"!

Check out a sneak peek of the performance here:

Don't miss it and more on tomorrow night's episode, "Prom-asaurus," at 8pm on Global!
