Katy Perry is headlining the Super Bowl halftime show this Sunday, a gig that the singer called "the biggest event of my career." Ahead of the game, Katy spoke to Billboard Magazine about everything from her plans for the big performance — including outrageous costumes and a few high-profile guests — and her thoughts on past halftime show performer Beyoncé, saying, "She's an icon. . . I'm not." She also touched on her reported "bad blood" with Taylor Swift after the release of 1989.
