Katy Perry Sets Fire To Blue Wig In Single Teaser

Katy Perry is seen setting fire to her famous blue wig in a video teaser for her forthcoming single Roar.

The pop star is seen standing in a darkened room in the 30-second clip, which is almost entirely soundless.

Titled Burning Baby Blue, it apparently heralds a "more mature" sound on her new album Prism - which Roar is the first single from.

She wore the blue wig during her California Dreams world tour, but is now said to be ditching her previous cartoony image.

The teaser ends with the hashtag #Roar (in a tiger-skin font) and the release date 12 August.

Her third studio album is slated for release in October.

We told you yesterday how Katy would like to run her own record label in future.
