Kate Middleton and Prince William previously confirmed that their first child is due in July, and a new report claims the royal couple has revealed the exact date to close friends.
The Duchess of Cambridge, 31, is currently seven months along in her pregnancy and a source claims she is expected to give birth to a royal heir on July 13.
"Some of William's closest pals were at a barbecue hosted by a family friend of the Royals recently," an alleged friend told Daily Mail. "They were all discussing the fact that Kate's baby is due to be born on July 13."
The baby will reportedly be born at the private Lindo Wing of St. Mary's Hospital in Paddington, which is the same place that William was born.
The couple is currently still in the process of picking baby names and Middleton suggested she is still unsure as to what sex her unborn baby will be.
"We have a short list for both [boy and girl] but it's very difficult," Middleton told Us magazine. "My friends keep texting me names."
Jessica Hay, who once shared a dorm with Middleton at Marlborough College, claimed in December that "Diana" is Middleton's favorite name. She speculated that the royal couple would name their first child Diana should they have a baby girl.
"Funnily enough, Diana is a name Catherine has always loved," Hay told Australian magazine New Idea.
The Queen of England announced in January that the royal heir will hold the formal title of prince or princess depending on gender.
In a formal decree issued on Middleton's birthday, Queen Elizabeth II declared that the Duke and Duchess of Cambridge's first child will hold a royal title and will also be referred to as His or Her Royal Highness, according to People magazine. The legal decision overturns a 1917 decree issued by the Queen's grandfather, King George V.
"It says, 'The Queen has been pleased by Letters Patentunder the Great Seal of the Realm dated 31 December 2012 to declare that all the children of the eldest son of the Prince of Wales should have and enjoy the style, title and attribute of royal highness with the titular dignity of Prince or Princess prefixed to their Christian names or with such other titles of honour,'" a declaration signaled in The London Gazette stated.
