Katy Perry burns her signature blue wig

Pop star Katy Perry is seen burning her signature blue wig and burying her "California Gurls" getup as she teases her forthcoming single, "Roar." Days after announcing her forthcoming album, "Prism," due out October 22, the pop star is teasing her next single with a pair of morbid promos.   In the first, released recently, Perry is seen holding a lighter and setting fire to her signature blue wig. In another, revealed Monday, she wears shades and a smirk as funeral onlookers mourn the death of her "California Gurls" persona. Perry calls the promo "The Third Coming."   By the looks of it, it seems that someone is revamping her image again. But even with a new look, Perry isn't likely to stray far from her signature sound. The singer reportedly got back together with longtime collaborators Dr Luke, Max Martin and Bonnie McKee on "Roar," which will be released officially on August 12. l
