AceShowbiz - The British royal family is really good at keeping secrets, but Prince William might have made a huge blunder by possibly revealing the gender of his and Kate Middleton's third child. It all started when the Duke of Cambridge was watching a soccer match at Villa Park stadium in Birmingham, England on April 10.

According to Mirror, William was so thrilled that his favorite team, Aston Villa, won the match that he accidentally revealed that he and Kate are expecting a baby boy. "I'm going to insist the baby is called Jack," he allegedly told John Carew, before adding, "Or Jackie." It is said that he was referring to outfielder Jack Grealish, who scored a winning goal during the match.

Kensington Palace has yet to respond to the reports.

As previously reported, temporary parking restrictions were put outside St. Mary's Hospital in London on April 9 as Kate is due anytime soon. The restrictions have been put up along South Wharf Road, suspending parking in the area between April 9 and April 30. Barriers have also been set up on the street in preparation for the hordes of reporters who will be present as Kate goes into labor.

Furthermore, the Duchess' medical professional team is on 24/7 call as the birth is now imminent. The team is led by Alan Farthing and Guy Thorpe-Beeston, who also helped Kate deliver Prince George and Princess Charlotte.

Kensington Palace will issue a statement regarding the baby's sex, weight and time of birth once she gives birth to her third child. If the birth happens in the middle of the night, the palace will not make any announcement before 9 A.M. U.K. time. The name of the baby will be announced when the royal couple returns to Apartment 1A of Kensington Palace.
