(CNN) -- Olivia Wise, a teenager who refused to let an inoperable brain tumor kill her spirit, died Monday. 

Olivia gained fame in the last weeks of her 16-year-long life when a Katy Perry song she recorded in a Toronto studio in September became a viral hit online. 

"She died peacefully in her home surrounded by the extraordinary love of her family," a family statement sent to CNN said. 

The teenager said that she didn't want people crying at her funeral, but that they should celebrate her life, her mother wrote in a letter to CNN. 

Her version of Perry's hit "Roar," which she recorded in September after learning there were no more treatments available, drew the attention of Perry after it was published on YouTube in October. 

"I was very moved and you sounded great," Perry told her in a video posted on YouTube. "I love you. A lot of people love you and that's why your video got to me. It moved everybody that saw it." 

Perry concluded with: "Keep roaring!" 

The international attention drew more than a million viewers to Olivia's song and helped raise $77,000 for the Liv Wise Fund that was started in her name in support of brain tumor research. 

The video shows OIivia sitting in a wheelchair in the middle of the studio, singing softly at first and struggling with her breaths. 

"'Cause I am a champion, and you're gonna hear me roar." 

Her energy grows and she smiles as she sings "I got the eye of a tiger, a fighter, dancing through the fire."
