Amy hopped on Instagram over the weekend to share her thoughts on A Quiet Place II — the sequel to John and Emily's 2018 blockbuster release.
"I loved every second of @aquietplacemovie even better than the first one which blew me away," she wrote. "Amazing to be in a movie theater."
However, Amy went on to make a swipe about John and Emily's relationship later in the comment.
"Although I've said for a long time I think Emily and John have a pretend marriage for publicity. But I still think you should see it this rainy weekend," she wrote.
However, it turns out that John actually saw the comment — and decided to leave one of his own.
"Thank you Amy!...for blowing up our whole marriage spot," he jokingly wrote.
Earlier in the week, John had actually opened up about his marriage to Emily, revealing that working with her on the Quiet Place movies was one of the best experiences he's ever had.
"Everybody was wondering how it would go working with your spouse, and so were we. We were very excited to see how that would go, and by 'excited,' I mean terrified," he said during a live Q&A session following Australian preview screenings for the movie.
"On the first movie, I found the best collaborator of my entire life," he went on. "She's not only the best actress, but she's someone who puts everyone at ease because she's so unbelievably prepared, unbelievably professional, and cares so deeply about the entire process."
"There were days when she wasn't shooting, and she'd still come to set, and she'd still see the shots and cheer us on," he added. "She is without a doubt, not only the best actress I have or will work with, but she's the greatest collaborator I've ever had."
