The couple are already the proud parents of 4-year-old Prince George and Princess Charlotte, aged 2. And while the gender of their third child is currently unknown, many have speculated that Kate could give birth to a baby boy - mostly due to her blue maternity wear and Prince William appearing to let the news slip. The Duke of Cambridge reportedly hinted that he and Kate are expecting a little boy while recently cheering on Aston Villa. He was spotted celebrating Jack Grealish's goal against Cardiff City, where he told other supporters what he wanted to name the impending arrival. According to The Mirror, he told fans "I'm going to insist the baby is called Jack" - before, after a pause, adding "...or Jackie".
