He is the Korean pop sensation that has taken America by storm.

The iHeartRadio Music Festival would not have been complete without him this year. K-pop king, Psy, gave Las Vegas a full serving of "Gangnam Style" by performing his viral song and dance on stage.

Who says you can't wear white after labor day? The singer and current dance phenomenon graced the stage in a full white tuxedo with purple sequins and matching purple sunglasses.

He started his signature anthem off with a bang and full on Gangnam dance moves. 

Everyone at the MGM Grand Las Vegas was PSY-ched and on their feet for Psy's performance, singing (in Korean!) and dancing along with him. Las Vegas has officially been Gangnam Styled!
