It's fun, funny and gone viral.... It's "Gangnam Style" and Britney Spears is getting in on it!

Appearing on The Ellen DeGeneres Show alongside her X-Factor co-star, Simon Cowell, Britney is surprised when Ellen brings the Gangnam Style creator Psy to the stage for a little impromptu dance lesson. Turns out Britney is a HUGE fan of the viral vid, and even tweeted about how much she "loved" it last month.

What's more impressive than Britney picking up the catchy moves so quickly, is the fact that she did it in heels!! Seriously, most women wouldn't even be able to walk in those things, let alone dance Gangnam Style!
