Newsround and CBBC do Children in Need 'Gangnam Style'
Here at Newsround we love nothing more than a reason to dress up.
And what better reason is there than Children in Need.
Check out the video above to see Ricky, Leah, Nel and Iain and Hacker from CBBC busting some moves gangnam style.
After cooling down Ricky, Leah and Nel posed in their outfits. Nice pout Ricky!
