Happy Birthday, Prince William!
Let's celebrate the daddy-to-be's last birthday before becoming a parent by taking a look at this flashback video of Will and Harry as little boys.
Although they don't sound particularly good, they certainly look cute as can be, and no doubt, the now 31-year-old royal will pass on some of those adorable genes to the future heir to the throne.
St. James's Palace said the Duke of Cambridge is celebrating "privately" (although it's safe to assume the doting hubby is focused on his expectant wife).
Earlier this week, the palace revealed the soon-to-be dad plans to be by Middleton's side when she delivers their child at St. Mary's Hospital in London—the same place where Princess Diana gave birth to Will in 1982.
The palace also said Will and Kate do not know the gender of their baby, but once the royal baby arrives, the announcement will be made public with a notice on the gates of Buckingham Palace which will also reveal the sex of their little one.
After Kate gives birth, the new dad will take a statutory paternity leave to spend time with his family before returning to work.
So let's celebrate the soon-to-be parents by also taking a look back at Kate as a little girl!
Consider the adorable pics and video proof the royal baby is going to be one beautiful bundle of joy.
