On top of that, we’ve previously learned that the episode will also include Brittany singing “Everytime” and Rachel (Lea Michele) taking on “Oops!... I Did It Again,”with a little help from Brody (Dean Geyer).
Now, Chord Overstreet (Sam) has revealed yet another of Season 4’s new Britney tunes: her 2009 dance pop track, “3.”
"We're doing '3,'" Chord told Billboard on the MTV Video Music Awards on September 6. "It's gonna be fun. It's all acoustic, kind of redone. It'll be fresh. There's a lot of really funny stuff in that episode. Lots of good dance numbers."
An acoustic version of that song definitely isn’t the sort of thing you would expect. We can’t wait to see how it ends up turning out!
