Kate Middleton and Prince William decided to officially tie the knot in 2011. They now have three kids, Prince George, Princess Charlotte, and Prince Louis.

Amid being simple and hands-off parents to the three young royals, they are also active senior members of the British Royal Family. The couple is even deemed to be some of the most popular and highly-praised royals.

While Prince William is a royal-born prince of Wales, the Duchess of Cambridge is a simple commoner. Royal experts claimed that it has been quite all too forgotten as she has been very natural in executing her duties and responsibilities as the future Queen Consort.

According to Express UK, though, a royal freelance journalist previously revealed that there is a reason behind Kate Middleton's excellence in living the royal life. In an Amazon Prime's content material titled, Kate Middleton: Working Class to Windsor', a documentary released in 2017, it was shared that before the Duchess' wedding to Prince William, Queen Elizabeth II met with her behind closed doors. 

It was explained that while the Duchess of Cambridge has had the support of the head of the British Monarchy, the Queen, reportedly, required her to take up "royal wife" lessons as preparations for her future life. This was said to ensure that Kate Middleton knew everything that she needed in all possible situations given that she did not grow up living the royal life.

The lessons, reportedly, included how to properly get out of a carriage or how to bend down royally, especially during engagements, "without exposing modesty." Even the smallest and tiniest details of certain actions were also said to have included in these lessons.

Things like how to sit, how to curtsy, who to do it for and not for, which utensils to use, and other things that most of the public would never think they need to learn, the royal journalist added.

Aside from the proper actions and etiquette, Queen Elizabeth II, reportedly, had "grave concerns" over Kate Middleton's work ethic. As per  Cheat Sheet, the British Monarch deemed it "unacceptable" as she was "disturbed" by the fact that the now-Duchess did not have a real job after college.

It was also revealed that this was one of the reasons why Kate Middleton and Prince William's engagement was delayed from 2007 to 2010 as the Queen reportedly required her to have an "identity" in her own right.
