A small town girl from Oklahoma, the comely Carrie Underwood sang her way through childhood and adolescence before vaulting to international megafame when she won the fourth season of American Idol. With her natural blonde hair, girl-next-door face, and melodically mouth-watering body, Carrie would have become a star even if she didn't have an angelic singing voice. Unfortunately, Carrie hasn't taken a page from the playbook of Shania Twain and donned rack-revealing get-ups in her videos, but fans of the country cutie were sated when she guest-starred on an episode of How I Met Your Mother, filling out stewardess and cavegirl costumes quite nicely. C'mon, Carrie! Show us your Gland Ole Oprys!
