"This county music legend has approved this Broadway performer to portray her in an up-coming TV movie. She's the apple of this singer's eye and was suppose to play another old and dusty singer for a project that apparently fell through."
No, they're talking about Kristin Chenoweth as Dolly Parton. I can tell by the clues.
"She's the APPLE of this singer's eye...." refers to
The Apple Tree. "was suppose (sic) to play another old and DUSTY singer..." refers to Dusty Springfield, which is another biopic that Kristin is going to star in.
