9-1-1: Nashville viewers have been clinging to LeAnn Rimes and Jessica Capshaw's onscreen chemistry - and the country singer isn't ruling out a possible onscreen romance between Dixie and Blythe. "That [idea] is my favorite. Jessica and I laugh so much about that," Rimes, 43, exclusively told Us Weekly before 9-1-1: Nashville's return on Thursday, February 26. "People love us together, which is awesome. We have so much fun together." Rimes has been having a blast sharing the screen with Capshaw, 49.
