Tonight's the finale of "Nashville" on ABC at 10-- Brad Paisley will make a guest appearance.

Tonight, Juliette will struggle with the death of her mother. Will the letter mom left behind help Juliette heal? Rayna will wrestle with whether to tell her oldest daughter the truth about her biological father.

Brad Paisley will sing with Rayna on the nighttime drama he seldom watches. Brad's wife Kimberly plays Peggy on the show. She's a bit of a seductress, so Brad's tuned out for most of the season.
