Katy Perry has rocked some crazy hairstyles. The singer, 27, has had pink, blue and purple locks. This time, her hair is bright orange for the cover of a French magazine. While Katy's hair certainly looks hot, chances are, the singer was wearing a wig. While the color is perfect for Fall, Katy's been spotted out and about recently, following her split from John Mayer, and her hair color has been a little more low key.
