Psy Makes Appearance at Madonna Concert in New York City [VIDEO]
Psy has quite literally almost taken over the world, or at least it seems that way! He's even been on stage at Madison Square Garden with Madonna to dance Gangnam Style!
Even the queen of pop isn't immune to the charms of Psy & Gangnam style! Watch as she gets busy onstage "riding the pony" as I like to call it!
