MANILA, Philippines – Madonna’s fans in New York City got a surprise treat from their idol when the worldwide Korean sensation Psy joined the veteran pop artist on stage at the Madison Square Garden on Tuesday night and danced the ubiquitous “Gangnam Style.”

What originally started as a mashup of Madonna’s “Give It To Me” with the infectious beats of the Korean hit suddenly turned into a “Gangnam” dance frenzy when Psy emerged from under the stage in his trademark shades and red suit.

Psy stayed on to join Madonna in her hit “Music.”

Clips from the concert found its way to the video-sharing site YouTube, including one from the wire agency The Associated Press.
