What does a country superstar do when she’s not performing on stage? Well, Taylor Swift’s apparently just like any other 18-year-old. When she’s not being dumped over the phone, she’s talking to cats, fighting with her brother or lip-synching to someone else’s music. (In this case, Swift is mouthing the words to Katy Perry’s “Hot N Cold.”)

In this video created for MySpace Celebrity, Swift’s fans get a chance to see what life is like on the road. They’re also given a behind-the-scenes look at her Crossroads performance with Def Leppard. Although she was clearly born after the rock band’s heydey, Taylor - who grew up with her mother’s musical taste - joined Joe Elliott on several songs for their October 6 concert.

Those interested in seeing the Def Leppard/Taylor Swift collaboration should tune into CMT on November 7.
