Prince William and Princess Kate apparently “broken the mould” as they capture the public’s attention with their display of affection and how they are still each other's “sweethearts."
Body language expert Darren Stanton provided insights into how the couple has evolved since their first meeting 20 years ago.
He highlighted their growing levels of "confidence and independence", and added "we have never seen senior members of the Royal family be so affectionate with one another in the public eye".
Speaking on behalf of Betfair Casino, Stanton said: "William and Kate are a very strong couple, and their relationship has continued to evolve and grow even stronger over the years."
"If we look back at photographs of Queen Elizabeth and Prince Philip, we would never have seen them holding hands or being tactile with each other."
The body language expert praised them for not shying away, "This shows how in tune William and Kate are with each other on an emotional level. They’re also not afraid to be open and honest through their body gestures about how they feel.
"They've really broken the mould, and there's a level of humour, playfulness and mischievousness to them when they want to be - which is really refreshing to see, " the expert added.
The Prince and Princess of Wales first crossed each other’s path at the University of St. Andrews in Scotland in 2001.
The two got married in a lavish wedding ceremony at Westminster Abbey on April 29, 2011.
The power couple shares three children, Prince George, Princess Charlotte and Prince Louis.
Prince William and Princess Kate are the two most senior members of the Royal Family, carrying out dozens of public engagements, giving a plethora of opportunities to catch a glimpse of the couple.
