Before selling out arenas, Blake Shelton learned how to command a stage at mostly girls' pageants in Oklahoma. "I learned that it was more to it than just coming up here and singing a song and walking off,” Shelton told 60 Minutes in 2014. "You got to perform but you also got to entertain. You got to make people laugh. You got to tell a joke or a story." Those early lessons helped shape one of country music's biggest stars. Shelton turns 50 today. #countrymusic #blakeshelton #country #oklahoma #pageant
