A source close to Kate Middleton and Prince William revealed that the royal baby is due to arrive on Saturday July 13, 2013.

Although the royal family has maintained privacy throughout the Duchess' pregnancy, a friend of the family spilled the beans on the due date and said that the couple cannot wait for the baby's arrival.

"Some of Kate and William's closest pals were at a barbecue hosted by a family friend of the Royals recently. They were all discussing the fact that Kate's baby is due to be born on July 13. Everyone was very excited," the source said according to The Daily Mail reported.

If the source wounds up telling the truth, the baby's due date will fall during the middle of the four-day Coronation Festival that will take place during July 11-14 to celebrate the 60-year anniversary of the Queen's crowning.

Middleton and William was married on April 29, 2011. The Duchess announced her pregnancy in December.

Since the news broke, Middleton has risen to one of the most popular pregnant women, as people all over the world has kept up with her everyday looks.

Enstars reported that on Saturday, Middleton was spotted showing off her growing baby bump, as she attended a wedding wearing a polka dress she wore two and a half weeks ago.

Although the Duchess nor Prince William have yet to confirm the baby's gender, reports indicated that Prince Harry revealed that the couple was having a baby boy.

"Harry has been telling everyone Wills and Kate are having a boy and how thrilled he is at the prospect of having a little nephew," a source said. "They're really working hard on baby names and think they have it sorted but they won't reveal anything to anyone -- not even Harry."

Enstars also reported earlier that rumors swirled that Middleton was having a girl after she was caught saying, "Thank you, I will take that for my d... for my baby," while accepting a teddy bear from a fan at an event in March.
