Katy Perry Performs "Firework" on X-Factor / by

Katy Perry hit the stage in the U.K. to perform her third single "Firework" on the hit show X-Factor. Vocally, it wasn't the best but she did put on quite a show with the fireworks and all. Check it out below.

Pretty nice right, the fireworks were nice but she seriously needs to work on those vocals of hers. I love the song but she butchered it. The video should be on the verge of premiering within the next few days so stay tuned.
