Psy and UN Secretary-General Ban Ki-moon praise each other

U.N. Secretary-General Ban Ki-moon says he's jealous of "Gangnam Style" rapper Psy.

The U.N. chief joked during a meeting with the South Korean rapper that he felt overshadowed by the star, whose video has scored more than  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 attempting a few of the trademark dance moves from Psy's viral smash video.

"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.

"You are so cool... I hope you can manage global warming," Ban told Psy, according to CNN.

He added, "You know, we have tough negotiations in the United Nations. In such a case, I was thinking of playing a 'Gangnam Style' dance, so then everyone can stop and dance. Maybe you can bring U.N. style."

Psy, whose real name is Park Jae-sang, also had high praise for Ban.

"For all the Koreans he is the guy, you know, in everyone's heart in Korea, the best among the best. To be here and he knows me, even the thing that he knows me is so touching right now, and he's saying he saw my video. He counted my video views," Psy said. "This is much more better feeling than when I did No. 2 on Billboard."

Earlier, Ban met supersonic skydiver Felix Baumgartner and spoke admiringly of his death-defying leap last week from a balloon 24 miles above the Earth. Baumgartner, whose jump broke the sound barrier and set a world record, offered to give Ban skydiving lessons.

It was a break from the conflict and wars the U.N. chief usually deals with. Ban's spokesman, Martin Nesirky, told reporters the secretary-general thinks it's important to engage different parts of society.
