Claire Cosby's cover of Katy Perry's Firework will melt your heart.
You may recognise little Claire from that time she appeared on The Ellen Show with Ellen Degeneres in the US singing the cutest rendition of the favourite Disney songs.
One again, Claire's teamed up with her dad Dave on guitar to cover Katy Perry's Firework.
The pair's YouTube channel caught the eye of the TV chat show host back in May, after the pair's videos racked up hundreds of millions of views on their channel, Claire and the Crosbys.
During Claire and Dave's time on the Ellen Show, they performed a version of Phil Collins' You'll Be In My Heart from Tarzan, but it was their cover of You've Got A Friend In Me from Toy Story that melted our hearts for good.
In return for hosting her performance, Ellen gave Claire and her family a trip to Disneyland – and a whole load of toys too.
Well, there you have it! Claire's got the voice of an angel...
