Warning: You may shortly need to go grab that box of tissues from the other room. We cried last October after watching Katy Perry's emotional performance with Jodi DiPiazza, a young girl living with autism, from Comedy Central's "Night of Too Many Stars." Now, Katy Perry's music has inspired another beautiful young girl, 16-year-old Olivia Wise. Living with terminal brain cancer, Wise recently visited a recording studio for the first time to record her own version of Perry's hit "Roar," and to say the words of the song took a whole other meaning ... that's an understatement.
With only a piano accompanying her, hearing Olivia sing that she's a fighter will give you goosebumps. And if that doesn't do it for you, the fact that Katy Perry has responded to the Olivia's video will have tears streaming down your face.
