'Glee' Prom Preview: Watch the Boys Sing a One Direction Song

There are only a few weeks left in this season of "Glee," which means that the seniors at McKinley High will soon be graduating. But first, they have to go through another senior year ritual: Prom.

This week's episode of "Glee" will have the kids attending their Senior Prom, and in true "Glee" style, the whole event was planned about a week ago. Then again, when Brittany is your class president, preparedness is not to be expected. Not that anyone else in New Directions is good at planning, seeing as they were writing their song for Nationals last year the day before the performance.

Of course, since Brittany is in charge of planning, the theme of the prom is dinosaurs, and New Directions will be performing live music. That includes a performance of One Direction's "What Makes You Beautiful," as Artie, Joe, Rory, Mike and Sam take on the peppy boy band hit. Good to see the bench players getting some screen time.

The episode will also feature songs like "Dinosaur" by Ke$ha (of course), "Take My Breath Away" by Berlin, and "Love You Like a Love Song" by Selena Gomez.

Watch the video of "What Makes You Beautiful" as sung by New Directions' non-seniors below:
