Sixteen-year-old Olivia Wise has recently gone viral on the internet after she posted a video of her covering Katy Perry's 'Roar.' Olivia suffers from an untreatable brain tumor that was discovered when she had a seizure last year.

 

 

Once the video started going viral, it eventually reached Katy Perry herself, & she was so moved by the young girl, she actually sent her a personal message.

 

 

Recently, Olivia Wise's family told CNN that her condition has worsened since the recording and she is now "drifting in and out of consciousness." A fund has now been started in Olivia's name with a goal of raising $150,000 towards brain treatment research.
