After wondering who Korean pop sensation Psy's surprise guest would be at last night's American Music Awards, the big reveal was far better than we could have ever imagined. Legendary rapper—and fellow dance craze innovator—MC Hammer joined Psy on stage to close the show with a medley of "2 Legit 2 Quit" and Psy's viral YouTube hit "Gangnam Style." InStyle.com caught up with Hammer after the performance to find out the biggest style question of the night: How did they decide to wear those iconic pants? "When Psy and I first talked about doing this together, one of the things he asked me was, 'Hammer, are you going to wear the pants?,'" he told InStyle.com. "And I said, 'Psy, I only wear the pants on special occasions.' I call this a special occasion, so I brought the pants out!" We're so glad he did.
