Carrie Underwood is the first country artist to take part in a public service campaign saluting teachers. Underwood is featured with three teachers -- her two sisters, Stephanie Shelton and Shanna Means, and their mother, Carole Underwood. The "Behind Every Famous Person Is a Fabulous Teacher" campaign pairs public figures with their favorite teachers. "Teaching was something that ran in my family," the singer said. "I have always admired my mother and sisters for making a difference in the lives of so many."
