It's official: Glee is doing Gangnam Style! The New Directions take on Korean rapper Psy's pop culture hit as one of their tunes at this year's Sectionals, and now we have a behind-the-scenes look at what to expect. Take a look at all the great dance moves, as Darren Criss (Blaine) and the rest of the New Ds give you a tour. And yes, this DOES confirm (again) that Blaine will be performing with the New Directions, not the Warblers, at Sectionals. Thank goodness.
