Dolly Parton has released a new memoir. The 79-year-old country superstar says her new book “Star of the Show: My Life on Stage” takes a look back at her seven-decade performing career. In a cover story for “People” magazine, Parton says she realized when she was putting the book together just how much she had sacrificed in her life. Parton – who lost her husband earlier this year – said, “I never had children,” but “I’m thankful that I got to see my dreams come true.” She says she’s now gearing up for what’s next, including her Broadway stage production “Dolly: A True Original Musical,” which opens next year.
