A terminally-ill teenager is getting the attention of the Internet with a cover of Katy Perry's "Roar."
Sixteen-year-old Olivia Wise and her family posted a video of her recording the cover on YouTube in mid-October. Since, it has garnered more than a half-million views.
According to "Billboard," Olivia suffers from an untreatable brain tumor that was discovered when she had a seizure last year. The cover starting spreading and eventually reached Katy herself, who was so moved she sent a video message to Olivia, giving her words of encouragement and support.
The girl's family recently told CNN that Olivia's condition has deteriorated since the recording and she is now "drifting in and out of consciousness."
A fund started in her name has been created, with a goal of raising $150,000 towards brain treatment research.
