Taylor Swift joined her supermodel BFFs at the Victoria's Secret Fashion Show to perform "Blank Space" and "Style" on Tuesday night. She was the first and last musical guest to hit the runway at the show, which was taped in London last week and also included performances by Ed Sheeran, Ariana Grande and Hozier. Even though the Victoria's Secret Angels took a stab at "Shake It Off" last week, Swift owned their stage.
