Country music's biggest stars are gearing up to celebrate Dolly Parton's 80th birthday at the Grand Ole Opry, but the singer will unfortunately not be attending the festivities. "Well, hey there, Grand Ole Opry family. I just wanted to say how much it means to me that you're all coming together again this year to celebrate my big ole birthday with some of my songs," Parton, 79, said in a video shared via the Grand Ole Opry's official Instagram page on Wednesday, January 7.
