Katy Perry dyed her hair blonde. Few weeks ago she changed her black hair color to red, which she now changed into blonde. Many people don't know but Katy is natural blonde so this hair color is bringing her back to her roots. It is little bit strange to see Katy blonde but it looks really good, and it is nice change from the dark hair. I wonder is she going to stop here or she is slowly going for platinum blonde. I can imagine her as platinum blonde and I think it would look great on her.
