Rapper PSY and UN Secretary-General Ban Ki-moon lavish praise on each other in NY

U.N. Secretary-General Ban Ki-moon says he is jealous of South Korean rapper PSY.

The U.N. chief joked during a meeting with the rapper that said he felt overshadowed by the star, whose video has scored over half a billion views on YouTube.

"I'm a bit jealous. Until two days ago someone told me I am the most famous Korean in the world. Now I have to relinquish. I have no regrets," Ban said.

The two lavished praise on each other at U.N. headquarters Tuesday, with Ban even risking a few of PSY's trademark dance moves from the viral smash video Gangnam Style.

"So now you have first and second famous Korean in the same building," PSY told reporters at a photo opportunity with the U.N. chief.
