This is so touching.
Katy Perry made and shared a heartwarming thank you message to a very brave teenager who is battling brain cancer.
The singer showered Olivia Wise with love after the inspirational teenager's cover video of Roar went viral.
Olivia's cousin Jeff Kassel says Katy's message has really excited the teenager. He said:
"The excitement that it’s been, the positivity…has been such an important boost, I’d say, during these really tough times. It means the world. It’s such an incredible thing and it really adds to Olivia’s legacy that she’s been able to inspire other people."
We're glad Katy's video was able to give this incredible young lady some joy in her life!
