The due date every royal family follower has been waiting for has been finally divulged. In a recent appearance, pregnant Duchess of Cambridge, Kate Middleton, has already revealed when she is giving birth.

When the expecting Catherine went to a charity event in Scotland with husband, the Duke of Cambridge, William, the most important detail of her pregnancy was revealed. Kate exclaimed that she is to start delivery in mid-August.

"It's around mid-July but apparently babies have their own agenda," jokingly admits the Duchess to reporters on April 4. As reported by Hollywood Life.com.

The Duchess has just entered her second trimester, and has recovered from violent vomiting disorder she had during the early stages of the pregnancy. As seen, the Duchess is looking more beautiful than ever, with the natural vibrant glow that comes with expecting a child.

Meanwhile, a source tells OK! Magazine that Kate's sister, Pippa Middleton, plans to arrange a "low-key" baby shower for her sister, eager to make use of her party-planning skills.

"While it's all going to be very relaxed and fun, Kate is hoping the queen will drop by because the two are remarkably close. They bonded big time and really enjoy each other's company. Since this is going to be a first for royals, Kate would love the queen to be part of it." said the source.

It is not customary in the United Kingdom to host baby showers, but since Catherine is known to be quite the non-traditional Duchess, she could give her sister the "go-signal." Unfortunately, royal experts suggest that a baby shower, with the attendance of the Queen, is not likely to happen.

This revelation is making fans of the Duchess even more excited, and followers will just have to wait on details about the gender of the royal heir.
