Grammy winner Barbara Mandrell has a lot to be happy about. With a string of No. 1 hits in the '70s and '80s, she starred in her own NBC variety show, Barbara Mandrell and the Mandrell Sisters, and is the only woman to receive two CMA Entertainer of the Year Awards. And come this spring, she will be inducted into the Country Music Hall of Fame. Crediting Barbara's success to "hard work and determination," her sister Louise said, "She didn't waver one inch from her priorities: God, country and family."
