It might get awkward for Brad Paisley on the set of the ABC drama Nashville when he shoots his guest-starring role for the season finale.

With his wife Kimberly Williams-Paisley playing Teddy Conrad’s (Eric Close) mistress Peggy Kenter, Brad admits he’s been reluctant to appear on the show. He says, “It’s a little odd, having Kim on there playing somebody else… It’s really good, but it’s disturbing to me, too close to what I do. It’s like if I was in the CIA, I don’t know if I’d watch Homeland.”
