Stars Party Gangnam Style Backstage at AMAs

By
BET's Rocsi Diaz acted as a special correspondent for ET at the American Music Awards on Sunday, getting up close and personal with the stars backstage, who were all big fans of Korean pop star Psy.
While Psy performed his hit song Gangnam Style, Rocsi used her Nokia Lumia 920 to capture the scene backstage where even Carrie Underwood was dancing along to the tune.
Psy was joined onstage by MC Hammer, who also accompanied him backstage for our interview.
"Twenty years ago, I saw MC Hammer on the TV in Korea and he said, 'You can't touch this.' And 20 years later, I can touch him," joked Psy, patting Hammer on the shoulder.
