Psy will perform on Dancing with the Stars (VIDEO)

Korean pop sensation Psy will appear on a May 21 episode of "Dancing With the Stars," continuing his inexorable march towards international super stardom. 

He'll perform his hit single "Gentleman" on the equally popular dancing-themed reality show as the season winds to an end, and fellow musicians Pitbull and Wynonna will be putting in appearances as well.

Only four contestants remain on Dancing With the Stars: Kellie Pickler, Derek Hough, Ingo Rademacher of General Hospital fame and Kym Johnson. 

You can watch Psy teaching Matt Lauer how to execute the "Gentleman" dance here. The track, which followed "Gangnam Style," set a Guiness World Record for the most-viewed video in a 24-hour time period. Impressive. 

In the extremely unlikely event you haven't already heard this track five millon times (perhaps, for example, you live under a mossy rock), here's the video of "Gentleman."
