The British royal firm is one of the most regal families in the world. The close-knitted family has been an institution known to be very hard to break into.

Kate Middleton’s entrance into the royal family was a heart-stopping event. Her marriage to the 3rd-in-line to the throne was one that Britons were keen to watch unravel.

Several concerns were, of course, expressed by the UK citizens as there has been a bitter history in the royal family, one that involves a royal wife.

So when Kate Middleton seemed to be so natural in her new duty as Prince William’s wife, people released a sigh of relief.

The Britons also largely noticed Prince Philip, the patriarch of the British monarchy, and Kate Middleton’s seemingly flawless relationship with each other.

Like Kate Middleton, the Prince married the current reigning sovereign of England. The difference between them is that Kate is a commoner, and Philip was born to reality, a member of the Greek Monarchy, and a cousin of Queen Elizabeth.

Royal experts have noted how natural the Duchess of Cambridge’s relationship with Prince Philip has been. This is a major sign that the mother of three has been welcomed into the royal family's deeper folds.

Body language experts have also studied that language between Philip and Kate during important events that the two have attended.

Kate has often made the Prince laugh, just like how the Duke of Edinburgh has made the Duchess laugh. Only a few people have made Kate break from her serious manner in events, and that his royal brother-in-law, Prince Harry.

According to body language experts, Kate Middleton seems to be natural around Prince Philip, and sharing inside jokes with each other is a good sign of their great relationship.

But they have also noted that Kate is still quite reserved around the Prince, just like she is with the Queen. This is noted to be a common in-law language.

Recently, Kate Middleton’s relationship with the Queen has also presented some good signs.

The Queen, who attended the RHS Chelsea Flower Show, which is one of Kate’s patronages, the Duchess of Cambridge, was noticed to have kissed the Queen’s cheek before curtsying, signals that the Queen has great trust in Kate.

It really seems that Kate Middleton is ready to be the Queen Consort in the future. She has been with the family for over a decade now and has flawlessly adapted the royal way of living.
