International star Psy may have hit it big last year with "Gangnam Style," but he had long ago made a name for himself in his motherland of South Korea with his unique and dynamic live shows.

Often, as a special performance during his concerts, the quirky Psy will don women's attire and hit the stage in the likeness of a famed female singer.

A crowd-pleasing favorite has been his spot-on rendition of Beyonce's "Single Ladies," but in his latest Seoul concert, Psy unveiled a new number for thousands of screaming fans.

On December 21 the rapper held the 2013 Psy Concert All Night Stand (also called Gymnastics on a Moonlit Night) at the Olympic Gymnastics Arena in Seoul were he addressed the crowd in a skin-tight red leotard to perform Sunmi's latest hit single "24 Hours."

Showing a superb handle on Sunmi's risque choreography, Psy shook his booty all around the stage and threw in more than a handful of sexy facial expressions for good measure.

The latest concert was the first in a series of five Psy will be holding at the Olympic Gymnastics Arena until December 24. A total of 60,000 fans are expected to attend the Moonlit Night concerts to see his latest cross-dressing performance live.

Check out the performance in the concert clip below as well as Sunmi's original.  How do you think he did?
