It's a mash-up that will get you out of your seat and dancing!
PSY performed his mega-hit "Gangnam Style" during Sunday's American Music Awards. Just as celebrity attendees The Wanted and Jenny McCarthy were getting down to the beat, a special guest joined PSY on stage -- MC Hammer!
The song segued into Hammer's "2 Legit 2 Quit," with both artists showing off some impressive dance moves, especially Hammer, who is 50 years old. Check out their performance below:
This isn't the first celebrity PSY's shared the stage with. Last week, the Korean pop star performed with Madonna in Madison Square Garden!
