There's no question about it, Psy's 'Gangnam Style' has invaded the brains of music lovers all over the world. Not even celebrities are safe from the infectious K-pop club banger, and the dance that comes with it? Forget about it. Even your grandma will have this one down by the time Christmas rolls around. 

Along with some help from his media-savvy manager Scoot Braun, Psy has been making the rounds with his electro rap hit. This exposure has led to celebrities from all over the entertainment industry catching the "dress classy, dance cheesy" fever, with people like 'Femme Fatale' diva Britney Spears, 'Saturday Night Live' regular Bobby Moynihan and Wolverine himself, actor Hugh Jackman, busting out their best 'Gangnam Style' dance moves.
