Katy Perry does something pretty shocking in the video teaser for her new single "Roar" — she sets her signature blue wig on fire!

We'd heard from the pop star herself that her new album Prism (which is due out October 22) was going to be a lot darker than Teenage Dream — but we certainly didn't expect her to completely cast aside her candy-coated past! We love that wig… and "California Gurls" for that matter!

Will her songs be as fun and addictive now that Katy's going more goth? We'll have to wait until the single drops on August 12 to find out!

Watch the clip below, and let us know what you think of Katy's new direction in the comments!
