Terminally Ill Teenager Video of a cover of Katy Perry's 'Roar' goes viral.

Katy Perry is giving fans a sneak peek at her new album Prism one track at a time.  After releasing her second teaser track, "Dark Horse," on Tuesday, the singer has now announced that yet another track is coming: "Walking on Air" will make its debut September 30.

Katy Perry gives us a little taste of what the video for her newest single 'Roar' is all about.

By now, you've formed an opinion on Katy Perry's new single "Roar," but what does Katy's boyfriend John Mayer think about the song?  Unsurprisingly, he claims he knew it was a smash as it was being recorded.

Now that Katy Perry has officially moved into the Prism era of her career with the release of her new single "Roar," she's truly left her Teenage Dream days behind...but one day, fans may have a crack at owning some of her iconic candy-coated looks from that time.

Katy Perry's new single rolled into iTunes with a "Roar" early Monday.
