Psy's new song will be accompanied by another wacky dance.

The South Korean rapper plans to follow his 'Gangnam Style' megahit with a new single called 'Gentleman' and revealed the track will be accompanied by a secret dance routine, which he hinted would feature a traditional Korean dance.

PSY told local television on Monday (02.04.2013): ''The new song is extremely fun and what I can tell you is the song title is 'Gentleman'.

''I can't tell you about the dance but all Koreans know this dance - but (those in) other countries haven't seen it''.

The music video for 'Gangnam Style' is now YouTube's most-watched clip and has made the 35-year-old star a global celebrity for his trademark 'invisible horse' dance.

However, PSY is remaining coy about everything else ahead of the new song's release.

'Gentlemen' will be available for Korean fans on April 12 and PSY will perform it in public for the first time on April 13.

The internet sensation has asked his fans to wear white to the concert, dubbed the 'HAPPENING'.
