Prince Harry tells friends Kate and William are expecting a boy

Prince Harry has reportedly told friends that Kate and William are expecting a boy.

Prince Harry is so happy about becoming an uncle he couldn’t keep the secret of the baby’s sex to himself.

The bookies are offering odds of 1/3 favorite on Kate Middleton having a girl and 5/2 for a boy, even though couple have made no official announcement about the baby due in mid-July.

But those odds may change after a source close to Prince Harry said: “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.

“He said the whole family were excited about it. Apparently Kate has always wanted a boy. They’re really working hard on baby names now and think they have it sorted.”

Princess Eugenie, Prince William’s cousin, has also been telling friends the baby is a boy, according to another royal insider quoted by the Sunday People.

The source said: “They won’t reveal anything to ­anyone – not even Harry. Of course, Harry’s been making up crazy suggestions and winding them up too.

“The close inner circle all know that it’s a boy and they’re busily buying gifts with a boy theme. There will be an awful lot if blue in their house.”

Although the Duke and Duchess of Cambridge have kept mum about the baby’s name, Kate Middleton, 31, has accidentally dropped a couple of hints about the sex of the child in recent months.

In March she appeared to suggest a girl was on the way when she given a teddy by a well-wisher during a walkabout in Grimsby.

Kate Middleton said: “I will take that for my d..” –and then stopped herself.

A nearby listener said: “You were going to say daughter, weren’t you?”

Kate replied: “No, we don’t know.”

Weeks later Kate Middleton appeared to drop another clue as she revealed she had bought a Bugaboo pram in light blue which could indicate the newborn would be a boy.

The pram’s color came to light when the duchess chatted to a group of Army wives at a reception on St Patrick’s Day.

Then Prince Harry was seen holding a blue teddy bear as he walked to Kensington Palace, the home he shares with Kate and William in London.

But there was a simple explanation – the bear had been given to him by a little girl while he toured Nottingham. She asked him to give it to Kate’s baby and he delivered it in person.

But another insider added: “Even though there’s a lot of gossip doing the rounds, there’s no way anyone can confirm it at the moment.”

The Sunday People claims that no decision has been made where Kate Middleton will have the baby, but the choice has been narrowed down to two hospitals.

Princess Diana Prince had William and Harry at St Mary’s hospital in Paddington, West London, while there is speculation that the child could be born at the Royal Berkshire Hospital – the birthplace of Kate Middleton and her sister Pippa.
