This video of five-year-old Addy becoming a pop star will melt your heart.  

In January 2013 Addy was diagnosed with stage IV cancer. In a bid to keep her spirits up while undergoing chemo and radiation treatment, Addy would sing and dance to some of her favourite songs on YouTube.

The little girl used Katy Perry’s hit song ROAR as inspiration to beat cancer.

This week her dream came true when she was given a makeover by children’s charity Make-A-Wish and became her idol, Katy Perry.

A spokesperson for the charity said: "While she was sick, Addy turned to arts and pop culture as a distraction from her symptoms and treatments.

"During her long hospital visits, Addy would spend hours drawing and, when she felt up for it, practicing her singing and dancing.

"Addy took inspiration from an array of performances by her favourite musicians on YouTube.

"When she learned she would be granted a wish by Make-A-Wish Mid-Atlantic– she asked to be a pop star performing Roar by Katy Perry (her favourite artist).

"Inspired by the lyrics to Roar, Addy fought and beat cancer, celebrating her victory with her wish come true - this incredible music video."
