Lots of excited fans patiently waiting for Katy Perry's new single to be released got a treat over the weekend when the song was leaked. "Roar" is the first release off of Perry's upcoming album Prism, set to come out October 22.

The leak occurred only a couple days before the song was officially set to be released; but for excited Perry fans, it wasn't fast enough. Being the leak happened only a few days before the set release, the record label has decided to officially release the song to radio stations - so look forward to hearing it on MIX 108 very soon.
