Carrie Underwood Performs 'Good Girl' on 'Letterman' (Video)
The country chart-topper belts her latest hit on the CBS late-night show.
She might be pageant queen-pretty and blonde, but there's a reason Carrie Underwood won American Idol and a boatload of music awards to follow: genuine talent, and a gift for picking really good songs.
The country singer belted out her latest single, "Good Girl," on Monday's Late Show With David Letterman, sporting an '80s-inspired black leather bustier and ruffled skirt.
The song -- from her new album, Blown Away, now the number one download on iTunes -- recalls Shania Twain in her sexy-rebel heyday, but the bluesy growl is pure Underwood.
