GameEarthColorful 341South Korean rapper-singer Psy performs during the 2012 iHeart Radio Music Festival at the MGM Grand Garden Arena in Las Vegas, Nevada in this September 21, 2012 file photograph. Psy, 35, released his much-anticipated new single titled "Gentleman" on April 11, 2013 hoping to repeat the success of "Gangnam Style" that made him the biggest star to emerge from the growing K-pop music scene. He will perform "Gentleman" in public for the first time on Saturday at a concert at Seoul's World Cup stadium but he has been coy about what dance to expect this time, except to hint that it is based on traditional Korean moves.
