Psy's new single will introduce a brand new dance craze.

The singer has promised fans his follow-up to viral hit 'Gangnam Style' will be just as ''rousing'' as his first international song and accompanied by yet another distinctive dance routine.

Discussing his new single on Korean TV, he said: ''I've been working and reworking on it continuously and I think the latest version will be the final one.

''This is another very rousing song. Its title is 'Gentleman'. The dance is one known to all Koreans but new to foreigners. This will be presented in PSYstyle.''

PSY plans to unveil the new song at a concert, dubbed the 'HAPPENING', on April 13 and has asked fans to wear white to the special gig held in his native South Korean capital, Seoul.

The 'HAPPENING' has reportedly cost $2.7 million and will be streamed live on YouTube.

It was previously reportedly PSY's next single was going to be called 'Assarabia', a slang word in his native country used to express satisfaction.

However, the amusingly-titled track caused a stir on Twitter after American journalist Steve Herman pointed out it could be misinterpreted as offensive to the Arab world.

PSY was quick to respond and insisted the song would to be re-titled and re-worded, as well as explaining the meaning of the word.

Steve tweeted shortly after: ''Received DM from @psy_oppa (he adds OK to quote): It's Korean slang & should be spelled assaraVia & ''that's not gonna be a single anyway.'' (sic)''
