Sightings:Newly Single Katy Perry’s Blue Style Statements (PHOTOS)

Though she’s smiling for cameras, there’s no doubt that Katy Perry has been quite blue sense her split from Russell Brand … at least style-wise! The “Part Of Me” singer has been complimenting her blue hair with an array of outfits in the same color.
