Kate Middleton Due Date Later Than July 18? Baby Will Be a Leo, Says Mom Carole Middleton [PHOTOS]

Pregnant Kate Middleton may be actually due to give birth later than everyone expects, according to her mother, Carole Middleton.

Reports indicated that the Duchess of Cambridge's due date was said to be July 13 after sources close to Kate and Prince William spilled beans on the date. 

Enstars reported earlier that friends of the couple gathered at a barbecue and said that the first time mother-to-be is due to give birth in the middle of July. 

"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. 

The Telegraph reported that Kate's mother, Carole told friends that her grandchild will be a Leo, which means the due date could range anywhere between July 24 and Aug 23. 

Though the baby's gender has yet to be confirmed by the couple, there are a fair amount of reports that have indicated Kate could be having a boy or girl.

A source revealed that Prince William's brother, Prince Harry spilled beans and said the couple was having a 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."

Back in March, rumors swirled after the Duchess was caught accidentally revealing the baby's gender when she accepted a teddy bear from a fan at an event. 

"Thank you, I will take that for my d... for my baby," she said. 

Prince William has remained quiet on his wife's pregnancy, but sources said that he is very excited for the baby. 

"He is looking forward to being a dad," a source said. "He's very excited about it.
