Tegan And Sara followed in the footsteps of artists such as Fall Out Boy's Patrick Stump, Paramore's Hayley Williams, and Jimmy Eat World's Jim Adkins last night, when they appeared as surprise guests alongside pop star Taylor Swift, at her sold out performance at the Staples Center in Los Angeles.
