Kate Middleton: Pregnant Duchess of Cambridge's Due Date Revealed to be July 13, During Coronation Festival [VIDEO]

Although Kate Middleton has been keeping specific details regarding her baby under wraps, the due date has finally been revealed.

The royal couple will welcome their newborn on July 13.

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

The due date falls during the Coronation Festival, a four-day celebration honoring 60 years since Queen Elizabeth took to the throne. The celebration runs from July 11 to July 14, which means the royal will most likely not be able to attend.

Opera Singer Laura Wright, who will perform in the gardens of Buckingham Palace during the festival, reportedly joked, "I had better not sing too many high notes... what if my singing made her go into labour?"

The baby will be born in the private Lindo Wing of St. Mary's Hospital in Paddington, where Prince William was born, with the delivery supervised by royal gynecologists Alan Farthing and Marcus Setchell, based on the report.

After it was announced that Middleton was pregnant, some thought that the baby may share a birthday with Prince Diana, who was born July 1. But it turns out the birth will be closer to the Duchess of Cornwall’s -  July 17.
