According to a report by TheDisInsider, Kacey has been in talks to take on the part of Vanessa - the human form of the villain Ursula.
The outlet claimed that the country singer has had several meetings with Disney about the project, although they add that there's a chance Kacey may also have passed on the role.
Neither Kacey nor Disney have responded to the speculation as yet.
If Kacey did get cast in the film, it would be her first major acting role. She's previously starred as herself in U.S. TV show "Nashville" and had a small musical role in 2018 movie "Wild Rose", but hasn't taken on a big project to showcase her acting talents.
