Psy will debut the follow-up to his hit Gangnam Style and according to Reuters, he will release a song called Gentlemen on April 12.

The South Korean rapper will perform the song for the first time at a concert on April 13 that will be broadcast on YouTube. Gentlemen will also have its own dance, just like the "invisible horse" step that became a trademark thanks to Gangnam Style.

"The new song is extremely fun and ... what I can tell you is the song title is Gentleman", Psy told a Korean TV station on April 1. "I can't tell you about the dance but all Koreans know this dance - but (those in) other countries haven't seen it."

Psy will perform his new song in Seoul's World Cup Stadium, and he asked concertgoers to wear all white clothes. He posted images of himself wearing white, in anticipation for the concert, on his Twitter page in late March.

A rumored audio video for the song has been released, and can be viewed below.

Gangnam Style is still the most-watched clip on YouTube. It debuted in the summer of 2012 and its official music video has over 1.5 billion views. Earlier in 2013 Psy collaborated with 2 Chainz, Tyga, Afrojack and Diplo on Gangnam Style remixes. Remix Style EP was released digitally on March 5. According to Republic, the reworked versions take the song "straight to the dance floor with propulsive production and uncontainable club energy."
