Dolly Parton won't be having a hard-candy Christmas this holiday season.

On Monday, NBC announced the country music legend will be joined by a slew of celebrity guests — including Jimmy Fallon, Miley Cyrus, Willie Nelson, Billy Ray Cyrus, Jimmie Allen, Zach Williams, Tom Everett Scott, Ana Gasteyer and Angel Parker — for her new Christmas special, Dolly Parton's Mountain Magic Christmas.

Parton, 76, will star in the special, which is described as "a modern-day movie musical."

"Dolly Parton's Mountain Magic Christmas is the frenetic backstage story and delightful on-camera results of Dolly's desire to uplift an exhausted world's spirits by sharing the unique 'mountain magic' she has always found in and around Dollywood at Christmas," reads the holiday special's description from the network.

The holiday show, which was first announced in May, will follow Parton through the making of the special-within-a-special before she becomes wrapped up in "a private journey into her past, guided by the mysterious appearances of her personal Three Wise Men," continues the NBC statement.

By the time she's ready to broadcast the fictional TV special, Parton has an epiphany and instead "shows the world that the real magic of Christmas lies in the hearts of the children we all once were, the realization that Christmas is about the people we share it with, and how her faith remains the common thread between Christmases past, present, and future."

Additionally, Warner Bros. Television will produce in collaboration with Magnolia Hill Productions and Sandollar Productions.

Parton is no stranger to holiday content, as she's previously released three Christmas albums: 1984's Once Upon a Christmas with the late Kenny Rogers, 1990's Home for Christmas, and 2020's A Holly Dolly Christmas.

Dolly Parton's Magic Mountain Christmas also marks the "Jolene" singer-songwriter's third TV film collaboration with NBC following 2015's Dolly Parton's Coat of Many Colors and its holiday-themed sequel, 2016's Dolly Parton's Christmas of Many Colors: Circle of Love.
