Taylor Swift Performs with Fall Out Boy's Patrick Stump

Oh, to be Taylor Swift and have special friends! The country-crooner hit the stage in New Jersey on Saturday for her Red Tour concert, and was joined onstage by none other than Fall Out Boy's Patrick Stump. The two performed the band's latest single 'My Songs Know What You Did in the Dark (Light 'Em Up)' together, while Swifty put on her best rock and roll self.
