Before an invitation only audience in Nashville in October, Swift will join her all-time favorite rock band on stage for a night that is sure to be a memorable one for the young star.

"Every time I've seen Crossroads on CMT I've always thought, 'If I ever get to do one of those, it HAS to be with Def Leppard!,' so this is really a dream come true for me," says Swift. "I have been screaming the words to Def Leppard songs for years so it's amazing that I'm going to get to share a stage with them this year!"

"How cool is this?! Country's hottest young star wanting to work with us!!" says Def Leppard's Joe Elliott. - more on this story
