McEntire was in the fourth season of her smash sitcom
Reba on the WB when Parton guested on an episode titled "Reba's Rules of Real Estate." The country legend was cast as Dolly Majors, the ruthless owner of a real estate agency at which McEntire's character, Reba Hart, lands a job.
As the episode goes on, Hart begins to see behind Majors' sweet facade and realize how cutthroat she is. She comes to find out that if those are the requirements, maybe working for such a power player is not the right move for her after all.
McEntire and Parton have teamed here and there for one-off musical performances over the years, too, and in an interview with E! in 2017, McEntire said she'd love to tour with Parton.
