Katy Perry burns 'Teenage Dream' blue wig in 'Roar' video

Katy Perry is turning over a new style.

In a teaser video for her new single "Roar," Perry lights the blue wig she wore in her "Teenage Dream" music video on fire. But why? Is she going to be showcasing a whole new persona with her new song that makes her want to leave all her cotton candy pop days behind her? Whatever the reason, she didn't seem especially sad to be "burning baby blue."

"WE DON'T NEED NO WATER LET THE BABY BLUE BURN," Perry tweets.

"Roar" will premiere on Aug. 12. Perry's new album "Prism" is due out on Oct. 22.
