Dolly Parton and Jimmy Fallon are getting into the holiday spirit early with their new Christmas jingle, "Almost Too Early for Christmas." The stars sing the catchy tune in a diner setting, acknowledging that some people may think it's too soon for Christmas decorations. Dressed in festive attire, Parton and Fallon are seen walking and dancing in photos from their upcoming Christmas special, "Dolly Parton's Mountain Magic Christmas." The special will feature a behind-the-scenes look at the making of the show and will include appearances from celebrity guests like Miley Cyrus and Willie Nelson. The special will air on Dec. 1 on NBC.
