McEntire said she's eaten at KFC all her life, since her days growing up in Oklahoma.
"We've maintained for quite some time that really anyone who embodies the spirit of the Colonel qualifies to play this iconic role", Andrea Zahumensky, chief marketing officer for KFC U.S., told Nation's Restaurant News.
Country music star Reba McEntire is the first women to ever play KFC founder and mascot, Colonel Sanders.
Colonel Sanders disappeared from adverts for almost 20 years but was brought back in 2015, when saw the role being played by a host of famous men including Rob Lowe and Ray Liotta.
"I said 'Holy smokes!'", McEntire told The AP. In commercials starting next week, McEntire dons the Colonel's famous white suit and black tie, but with a twist.
"Absolutely nothing's changed", she croons. 'I got a big kick out of it'. Then, after thinking about it for a second, McEntire corrected herself: "Probably not". "I'm definitely not a woman".More news: Keita Bates-Diop questionable for Thursday's game vs. Penn State

"I thought the transformation was really amusing", said McEntire, who will appear in the ads until the end of April. 'KFC has been a part of my life forever'.
McEntire is the latest in a long line of actors to play Sanders in KFC ads over the last two years.
Now, with a debate about gender diversity touching industries from Wall Street to Hollywood, Yum has shifted course as it rolls out ads touting its new smoky mountain barbecue chicken.
The original Colonel Harland Sanders died 36 years ago.
McEntire's ads will be to promote the fast food restaurant's new Southern Mountain BBQ.
