'Gangnam Style' iHeartRadio Music Festival Craze: Psy takes Las Vegas by Surprise [VIDEO]
"Gangnam Style" singer Psy made a surprising appearance at the iHeartRadio Music Festival in Las Vegas Friday putting the audience to dance to the popular horse riding choreography.
Psy appeared at the MGM Grand Arena in Las Vegas with a smile on his face and his signature slicked back hair. He was wearing a white suit with shiny lapels and sunglasses.
His performance was not part of the official lineup.
"From now on, make some noise, come on!" the South Korean rapper shouted to the thousands in the audience, this time performing without backup dancers.
This is Psy's second big appearance at a major music event in the United States. He appeared early September in the MTV Video Music Awards 2012.
