Katy Perry Lets Out 'Roar' at Halftime

Did Katy Perry diss Taylor Swift, or just let out a huge roar? The pop princess emerged for her Super Bowl halftime show in a flaming dress riding an enormous mechanical beast and singing her hit song "Roar," reports the New York Times' Super Bowl Blog. As she sang "you're gonna hear me..." the lion or tiger (it's not clear which) reared back on its hind legs and roared. Her multicolored, fast-moving, all-glam show included "Teenage Dream" in an island paradise setting and "I Kissed a Girl" with Lenny Kravitz while fire bellowed from the stage. Perry also danced with chess pieces on an enormous checkered board and performed alongside Missy Elliott. The highlight? America's pop queen flying over the field singing "Firework" as fireworks erupted over the stadium.
