'World star' Psy sang "Gangnam Style" in front of President Obama, but there're was no 'horse-dance' performance together.

Yesterday, Psy performed the finale at the "Christmas in Washington" 2012 concert.

He wore a sparkly red top to match the mood of the holidays.

President Obama and his family watched the show but did not dance along to the 'horse-dance'.

This show will air on TNT on December 21.

This year is the 14th annual "Christmas in Washington" and is famous for having the president attend every year.
