Psy has unleashed the follow-up single to smash hit 'Gangnam Style'.

The Korean became a global star overnight when he released the track last year, spawning a dance craze in the process.

The singer has now debuted new single 'Gentleman' and he has been unveiling it across the world.

Psy previously hinted that the track could feature a new dance routine, but one that might already be known in his homeland.

The song features the tag-line: "I'm a mother f**king gentleman."

Psy meanwhile is due to perform at the Seoul World Cup Stadium tonight (April 12).
