After Aston Villa player Jack Grealish’s winning goal against rivals Cardiff City, William told fans: “I’m going to insist the baby is called Jack,” reports the Mirror. After a pause, William then added, “…or Jackie.” Following the game, Grealish gave William his game-winning shirt — a gift that would be perfect to display in the royal nursery!
