Swift's rep, Tree Paine, tells PerezHilton.com:
Wow. Wow. Wow.
Kanye is straight-up INSANE!!!!!
It wouldn't be a country music event without an appearance from Keith Urban!
Keith did his hit song Cop Car, surrounded by his fans who were lucky enough to be in Nashville for this incredible night!
They were so close, they could reach out and touch Keith! We're super jelly!
