Korean pop star Psy continues to take over the world with his 'Gangnam Style' smash. This week, as he visited 'Ellen' to perform the song live, it was revealed that he didn't recognize Drake when the Canadian rapper approached him at the MTV Video Music Awards.

XXL quotes Psy describing his encounter with Drizzy at the award show: "I was at the VMA and I was sitting down at the chair, and someone asked me, ‘Hey, how much your music video cost? Hey, who wrote the track?’ I said, ‘I wrote the track,’ and he said, ‘Oh, yeah? Wow.’ But I didn’t recognize who he was. And then suddenly when they announced, ‘The winner is Drake,’ and then he stands up, and he walks away. I was like, ‘Oh! Is that Drake?’ So Drake asked me something and I was like, ‘Who is he?’ Am I nuts? So after he came back, I said, ‘Oh, Drake, I’m so sorry.’”

The Korean star lived up to his "Dress classy and dance cheesy" mantra by showing up to 'Ellen' to perform the full song, just one week after he stopped by the show to teach Britney Spears how to do the 'Gangnam' dance. He danced with about a dozen backup dancers and rode his invisible horse into the audience, where the entire crowd bounced along.

After his previous performance on the 'Today' show, 'Gangnam Style' shot up this week from No. 64 to No. 11 on the singles chart and shows no signs of slowing down. While the track seems like a novelty hit, industry insiders believe Psy is no flash in the pan. He has been a K-Pop star for more than a decade, and Justin Bieber's manager, Scooter Braun, recently signed Psy to an American record deal.
