Katy Perry just posted a video giving fans an intimate look backstage at her California Dreams tour! In the footage, a makeup-free Katy does a goofy jig during vocal warm-ups, wears a peacock outfit, and puts in long hours to get her show just right — and it looks like it all paid off. Katy will be touring in the States come June, but for now, fans can look forward to her newest music video "E.T." featuring Kanye West which debuts on MTV tomorrow. Get a sneak peek at Katy in her strange alien attire for the video's shoot!
