Psy taught the "Gangnam Style" moves to the Chief of the United Nations Ban Ki-moon on Tuesday during a meeting with South Korean rapper Psy in New York City and it was all captured on video.
Ban Ki-moon joked with reporters about being jealous of Psy.
"I'm a bit jealous," Ban told reporters. "Until two days ago someone told me I am the most famous Korean in the world. Now I have to relinquish."
"We have a tough negotiations in the United Nations. In such a case I was also thinking of playing 'Gangnam Style' dance so that everybody would stop and dance, maybe you can bring U.N. style," he said.
Ban Ki-moon posed with Psy for pictures imitating Psy's landmark horse dance, made famous in the song. However, the U.N. Chief did not attempt to dance the entire choreography.
"I know that you are here to see me dance but don't worry - I cannot even imitate your movement," Ban said.
The "Gangnam Style" music video has been viewed more than 530 million views on YouTube since it was posted by Psy in mid-July.
The hit launched Psy career overseas as he appeared in numerous TV shows and big music events in the United States.
Mr. Ban Ki-moon also met with Austrian skydiver Felix Baumgartner, who jumped from the edge of space earlier this month breaking the speed of sound in an unprecedented free fall witnessed from people from all around the world.
