The adorable Claire Crosby is back with another cover, this time she's taking on Katy Perry's 'Firework'.
The video which was only uploaded a few days ago has already been viewed hundreds of thousands of times!
Claire's dad wrote that "Claire loves Firework by Katy Perry. I realized just how much she loved it while lighting fireworks a few weeks ago on the 4th of July. She was singing it at the top of her lungs as we waited for fireworks. Hope you enjoy her best Katy Perry impression."
