He is also scheduled to fly over to Europe for the MTV European Music Awards where he was nominated for Best Video against top singers like Rihanna, Katy Perry and more.

The 5-hour long iHeartRadio Festival audience did not expect to see Psy perform Gangnam Style.  He was not even on the list of performances.  However, it was a pleasant surprise when he did jump onto the stage with his signature fashion suits and dark sunglasses.

"Dress classy, dance cheesy" is the perfect description for his song.  He performed with enthusiasm and the crowd shot videos with their phones and danced along.

Psy is scheduled to return back to Korea on September 25th, but it will no be long before he comes back out to the U.S. and Europe.  

The "Gangnam Style" music video currently has nearly 250 millions views.
