How adorable is little Addy? Watch the world premiere of her very own music video to Katy Perry's megahit "Roar." The 5-year-old was diagnosed with stage IV cancer one year ago. Addy spent a lot of her time in the hospital watching performances of her favorite pop stars on YouTube. Make-A-Wish Mid-Atlantic granted Addy the opportunity to shoot this super cool, highly-produced music video. We're ecstatic to report Addy beat cancer and this music video is now a celebration of her victory.
