Korean pop sensation ups trackside heat

Formula One fans got a slice of 'Gangnam Style' on Sunday when pop sensation Psy appeared at the Korean F1 Grand Prix in Yeongnam, South Korea. The Korean rapper, who has shot to international stardom after a music video of him doing the quirky hording-riding dance went viral on YouTube and stormed to number one in charts around the world, gleefully waved the chequered flag at the end of the race to give Red Bull F1 driver Vettel the victory in the race.

Earlier in the day, the chubby star also gave Vettel and fellow Red Bull driver Mark Webber a lesson on how to do the dance - much to the delight of fans and the media.
