We all know Ellen DeGeneres is a dancing machine on her show. Unless Justin Bieber is on the show she's usually the one dishing the moves. This time around she was being taught a few dance moves by the crazy Korean artist Psy.

The X Factor judge told Ellen she had tweeted about the pop star and sure enough, seconds later on stage was Psy himself!

Psy's 'Gangnam Style’ tune exploded on Youtube generating over 152 million views to date. The bizarre video has inspired countless re-makes including one that got 14 lifeguards fired for filming on city property without permission.

Check out Ellen and Britney busting a move, 'Gangnam Style’!

This guy is my new hero!
