Katy Perry has released the video for her new single Firework, and the starlet tweeted last night that she's dedicating it to the It Gets Better campaign for bullied youth because "everyone has the spark to be a firework."

"People are coming back and almost adopting it as their own anthem, and it's hard, I think, to write an anthem that's not cheesy," she told MTV News. "And I hope that this could be something in that category. I hope this could be one of those things where it's like, 'Yeah, I want to put my fist up and feel proud and feel strong.'"
