Psy has cancelled a scheduled appearance at Tampa's Jingle Ball for a gig playing for the President and First Lady! On December 21st, Psy will get the chance to realize a dream he's already talked about: teaching President Obama how to dance Gangnam Style. YG entertainment fills in a few details: “It is true that Psy will be the closing act for the ‘Christmas in Washington 2012′ concert, but we’re not 100% certain if he will have the opportunity to perform the ‘horse dance’ in front of the President and the First Lady. However, since they’re planning to attend, the probability that he will is very high.“ Do you think Psy will get the President to horse dance? Either way, congratulations Psy!
