The Duke and Duchess of Cambridge are the picture of marital harmony, but they've been snapped holding hands less than a dozen times in a decade.
Why? Simply because they take their royal "jobs" very seriously and don't think public displays of affection are very professional.
"There is no actual etiquette or royal protocol that says the couple must refrain from PDA," royal etiquette expert Myka Meier told People magazine.
"The likely reasoning is more that while the couple are working representatives of British Monarchy, they are likely to show very little PDA, if any, to remain professional during their designated roles."
Sometimes, though, especially during more relaxed events – like the 2012 London Olympics – the couple do let their guard down and let their love shine through. And we just love it when they do!
