Looks like ABC's Nashville is becoming a family affair for the Paisleys.
Kimberly Williams-Paisley is now a show regular, playing the wily mistress who's (spoiler alert!) sleeping with country star Rayna Jaymes' mayor husband.
Now, Kimberly's real-life country star hubby, Brad Paisley, is set to play himself on the season finale, several media outlets report .
Brad will perform a song with Rayna (played by actress Connie Britton) and Deacon (Charles "Chip" Esten).
The episode airs May 22.
