An emotional Taylor Swift opened up about the foiled terror plot to bomb her concert in Vienna last year. Swift talked about the drama with fellow pop singer Ed Sheeran. Swift broke down in tears after meeting with the families of the three little girls who were stabbed to death in England during a Taylor Swift-themed dance class. The docu-series "Taylor Swift: The End of an Era," gives an intimate look at how Swift pulled off the highest-grossing tour of all time. #TaylorSwift #ErasTour #Concer
