Dressed in the founder's signature white suit, black string bow tie and glasses, McEntire sings a honky-tonk tune about the new southern-inspired menu item that blends barbecue recipes from Memphis and the Carolinas.
She's now starring in four ads, which will air in the USA from Sunday 28 January until the end of April.
A rotating cast of famous names have portrayed the Colonel since 2015, including comedians Darrell Hammond, Norm MacDonald, Rob Riggle and Jim Gaffigan. At one point, the police run in to take the noise down a notch but end up dancing with the rest of the group anyways. "I'm definitely not a woman".
McEntire reveals how she's "been in love with KFC forever", and how her upbringing in Oklahoma helped her formulate an accent that is "a little thicker than I talk normally" for the role. "Just the same old Colonel with a new flavor of fried chicken", features The Grammy-winning singer crooning over smoky BBQ chicken in a Western styled saloon.
What do you think of Reba as the new Colonel Sanders? "We picked Reba McEntire because she is the flawless fit for KFC and Smoky Mountain BBQ". She's also "eaten KFC my whole life" because it's "American" and, in her mind at least, "wholesome".
"I thought the transformation was really amusing", she added.
