Carrie Underwood performed her hit single ‘All-American Girl’ on stage during the 2008 CMT Music Awards at the Curb Events Center at Belmont University on Monday in Nashville, Tennessee. The 26-year old American Idol champ closed the entire show in a cute baby blue baby doll dress. Single, dating or in a pretty serious relationship, Carrie looks really good and sings really well. Earlier that night on the red carpet, Carrie rocked a purple one strap mini. It looks like she’s still playing on the cute side of her image. But it’s Carrie Underwood – she always going to be cute!
