John Gammon has kept his personal life private, rarely commenting on it. The actor has never been spotted with a wife and has never been seen courting anyone. John appears to be single in real life, despite having an on-screen romance with Sue on the ABC sitcom The Middle.
He has not revealed any of her personal information on social media networks to this day. The attractive actor does not appear to have an Instagram account, nor does he appear to have one on Facebook, Twitter, or even Linkedin. He seemed to prefer keeping her personal life as private as possible.
