Are Prince William and Kate Middleton expecting a little prince?Prince William and Prince Kate Do you want to have a little prince this time?

Prince William may have just accidentally revealed whether he and Kate Middleton are having a girl or boy.

After celebrating a winning goal from Aston Villa soccer player Jack Grealish, the royal dad reportedly told fans, "I'm going to insist the baby is called Jack."

He then paused, realizing he may have slipped up, and said, "...Or Jackie." Then he paused for a moment, realizing that he might have missed, "or named Jackie (girl's name). "

While "Jack" or "Jackie" isn't a widely-predicted royal baby name, this is a major hint that William and Kate are having a boy. But whether it is called "Jack" or "Jackie" is not the name of the royal baby that everyone speculates. Perhaps this is a hidden evidence that Kate is about to give birth to a boy.

Following the game, Grealish gave William his game-winning shirt — a gift that would be perfect to display in the royal nursery! After the game, Greenris gave Prince William his game-winning shirt — a gift that would be perfect to display in the royal nursery!
