Kate Middleton and Prince William Having a Baby Boy?

Rumors are circulating that the Duke and Duchess of Cambridge's first child will be a boy. Prince Harry leaked this information before the July due date to British press.

"Harry has been telling everyone Will and Kate are having a boy and how thrilled he is at the prospect of having a little nephew," an insider told the Sunday People newspaper.

The 31-year-old Duchess told the media in March that she didn't know the sex of her child but that she wants a baby boy, while her husband Prince William wishes for a girl.

Another source told the newspaper that Kate and Prince William haven't told anyone anything yet. "Even though there's a lot of gossip doing the rounds, there's no way anyone can confirm it at the moment. Kate and William are really enjoying the speculation but are keen not to give the game away," the source said.

The gender of the royal couple's baby has been a well-kept secret. Many speculations have been made; the Duchess' every movement and words are interpreted by fans and the media.

However, in March, Kate gave the impression that the child will be a girl, according to InRumor.com.

Diana Burton, a woman in Grimsby, gave Kate a teddy bear while she was visiting. The Duchess thanked her and said "Oh is this for our d..."

The woman asked: "Did you say my daughter?"

Duchess Catherine quickly covered her tracks and told the woman she didn't know the gender of her baby. Fans were not so easily convinced.

Recently, Kate bought a lilac stroller, a unisex color. Rumors are likely to continue until the royal child is born in July.

In other news, the man who wrote the music for the couple's royal wedding two years ago has written a lullaby for their unborn baby.

According to The Scotsman, the composer Paul Mealor said: "After writing music for the Royal Wedding it seemed natural to provide the musical accompaniment for the next stage of the royal couple's journey together."
