Weiss also said that he's known his girlfriend's grandparents for four years, but he never expected to see them take a picture like this one. "It's definitely not their typical behavior. They are very respectful and when I saw the photo, I couldn't believe they did it."
Still, he says he shouldn't have been too surprised. At the Nashville wedding, the groom's grandmother was "a dancing queen, we can just put it that way," Weiss said. "She was out there dancing the entire night, and she was loving dancing with the groomsmen."
