While Katy Perry's "California Dreams" tour doesn't hit the U.S. until June, a new video posted on her official YouTube chronicles the singer's tour rehearsals at the Forum in Los Angeles. Watch below -- or as Perry says in the clip, "let's go watch some lasers and stuff."
According to the clip, Perry and her team had a mere four days of rehearsal to gear up for the world tour, which currently has performances scheduled until early November 2011.
Perry's latest single "E.T." reached No. 1 on this week's Hot 100 chart, but as she boasts in the clip, "you're not a real pop star unless you have a bling mic."
