Katy Perry looked stunningly gorgeous as she was spotted on her way to the Jimmy Kimmel Live show in West Hollywood to promote her new documentary 'Part Of Me'. She wore a purple floral mini dress from the Temperley London Fall 2012 collection, that looked strikingly pretty with her matching hair. Katy also wore black Christian Louboutin platform slingbacks. Her purple hair almost seemed to blend into the sheer sleeves of her dress. When asked by Jimmy Kimmel how does she get her hair so purple?, Katy replied, "I squeezed the purple Teletubby all over my hair, and went out in the rain."
