While the buzz over Katy Perry was building, she went on the next step of promoting the album, undergoing a two-month tour of radio stations. Katy Perry album's official lead single, "I Kissed a Girl", was released on May 6, 2008. With the song climbing atop the charts, Katy Perry embarked on the annual Warped Tour music festival, which Katy Perry management used to "establish her as a credible performer and make sure she (Katy Perry) wasn't seen as just a one-hit wonder".
