Hi everybody. I'm a new member. Katy Perry who sings I kiss a girl. At the end of the song at her concerts, she dose a stage dive into the crowd. The crowd gose wild, and you can see somebody grab her ankel, and take her shoe off. when she gets back on stage, she takes the other shoe off, and throws it into the crowd before she leaves. Go to you tube and type Katy Perry stage dive. The first three videos are awsome.
