'Tis the season to be Dolly! CMT and Dolly Parton have announced a festive, all-day Christmas extravaganza on Saturday, December 5.

The full Dolly channel takeover includes a holiday movie marathon, classic music videos, a full episode of CMT Hot 20 Countdown, personal anecdotes from Dolly and more.

Throughout the marathon, fans can expect some fun Dolly surprises including personal holiday reflections and Christmas memories from Dolly herself, a tease for her upcoming CBS special and much more to make this ‘Holly Dolly Christmas’ unforgettable.

Kicking off the holiday festivities will be an entirely Dolly-themed episode of CMT Hot 20 Countdown at 9am ET/8am CT. Hosted by CMT’s Katie Cook, the show will welcome Dolly as its only guest of the weekend to chat about her new album, A Holly Dolly Christmas.

The country legend will also preview the holiday movie marathon and take a look back at her 30+ year history with CMT.

The main event, CMT’s Holly Dolly Christmas Movie Marathon, will begin directly following the episode and feature the most iconic Dolly films of all time: Coat of Many Colors, Christmas of Many Colors: Circle of Love, Unlikely Angel and Steel Magnolias.
