Katy Perry Checks Out John Mayer at the Hollywood Bowl
The "Roar" singer looked cute in a floral print minidress and black heeled ankleboots as she headed inside with a black jacket draped over her arm.
Getting creative with her music promotion, the 28-year-old actress decided to make her way into the Halloween costume biz.
Earlier this week, Katy posted a photo of an outfit similar to the one from her music video with the caption, "WHO'S READY FOR HALLOWEEN?! Get my ROAR costume HERE."
