This 4-Year-Old And Her Dad Covered Katy Perry's 'Firework,' And It's The Most Adorable Thing Ever

Claire Ryann Crosby might be known for her covers of Disney movie songs, but now she's crossing into new territory: pop songs.

The 4-year-old singer recently sat down with her father, Dave Crosby, to film a cover of Katy Perry's "Firework" for The Ellen Show's YouTube channel.

Claire's version of the Katy Perry hit is purely acoustic. Her dad plays the guitar as she articulates every single lyric from "Firework," whispering most of them before she enthusiastically hits the chorus.
