British newspaper Sunday People first broke the news, and since then it has spread like wildfire through media outlets around the world. If the rumors are true, Duchess of Cambridge Kate Middleton and husband Prince William are expecting a baby boy. The soon-to-be parents are preparing for their bundle of joy, due in mid-July and helping them along is renowned composer Paul Mealor who wrote a lullaby just for the royal heir. 

Mealor, who wrote music for Kate and William's wedding collaborated with classical artist Hayley Westenra to create a royal lullaby for said royal heir, entitled "Sleep On." While Mealor takes credit for writing the song, Westenra will record it.

"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," Mealor said in a statement.

"Paul and I got together to work on a song...in honor of William and Kate's new arrival as it's such a joyous occasion which we can all celebrate," Westerna said.

These legendary musicians are certainly not the only ones looking forward to the new baby. Sunday People reports that Prince Harry has reportedly spilled the beans to close friends that he will soon have a nephew in his life.

It's alleged that an unnamed source who is close to the Prince has revealed that "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."

"The close inner circle all knows that it's a boy and they're busily buying gifts with a boy theme," the source said. "There will be an awful lot of blue in their house."

And although Kate and William refuse to confirm the gender of the baby, there are rumors that Kate recently purchased a light blue Bugaboo stroller. The fact that the opted for blue instead of a more gender-neutral carriage have lots of people buying into Harry's alleged gossip about the baby being a boy. So much so that Ladbrokes, a British only betting and gaming company reported that more than 750 bets have been placed on the royal baby being a male.

A spokesman for the company has said that this is "an unprecedented amount of bets."

"A huge gamble is now developing on the royal baby to be a future King," said Jessica Bridge of Ladbrokes. "Punters are incredibly excited by the latest news and are rushing to put the money on a boy."
