Taylor Swift performed “I Knew You Were Trouble” at the 2013 Victoria's Secret Fashion Show. She was one of the show's featured musical performers in New York City.
Swift also performed “ได้?” No—her other confirmed performance at that show was “My Songs Know What You Did in the Dark (Light Em Up)” with Fall Out Boy. The show combined live music with themed runway sections and Victoria's Secret models.
The event was recorded in November 2013 and later broadcast as a television special. Its musical lineup also included Fall Out Boy, A Great Big World, and Neon Jungle.
The song title is sometimes confused with Swift's other fashion-show performances because she appeared at more than one Victoria's Secret show. The question specifically identifies the 2013 event.
