Is the couple expecting a Jack... or Jackie?

Careful there, Prince William!

The 35-year-old royal may have revealed the gender of his and Kate Middleton's third child while celebrating his soccer team's championship win on Tuesday night. 

William got a little caught up in the excitement after Aston Villa player Jack Grealish's winning goal against their rivals, Cardiff City, telling fans, "I'm going to insist the baby is called Jack," The Mirror reports, adding after a pause, "or Jackie." 

William and Kate have yet to reveal the name they've picked out for baby No. 3 -- or whether it's a girl or boy. We won't have to wait long to find out, however, as Kate is due to give birth this month. She and William are already parents to 4-year-old Prince George and 2-year-old Princess Charlotte. 

Observant fans have already caught several clues that the Duchess of Cambridge's due date is approaching. Earlier this week, workers started putting up media barricades on the street outside the Lindo Wing of St. Mary's Hospital in London, where Kate is scheduled to give birth.
