This somewhat frumpy teenager turned into the beautiful swan who first came to America's attention over 10 years ago. She wasn't too far removed from high school at that point, but she had a voice that rivaled the best in pop music.

Only recently has she turned to country music. After lending her voice to two successful duets, she released her own single with a country legend. Good friends Blake Shelton and Reba McEntire have helped steer her career as she transitioned. Do you think you recognize the Texan in this yearbook picture?
