When Jon Pardi's wife, Summer, tried to tell him that they were pregnant, it took a few minutes for him to realize what was going on. Summer planned to surprise him by attaching a baby on board sign and a positive pregnancy test to the back of their brand new boat. She then told him there was a big scratch on the boat. "Even with the baby on board sign and pregnancy test, he still didn't get it," she says in a video posted to social media. "He thought I was just making fun of him because the boat was his new baby." Once Jon realized what was happening he went into full dad mode. "5 minutes later he was blasting 'Baby Shark' in the kitchen," Summer wrote in her post. The couple have not announced the sex of their baby, but in her Instagram Stories fans can guess whether baby Pardi will be a boy or girl.
