The Royal Kiss: What Does It Tell Us?

Prince William and his new bride Kate, now the Duke and Duchess of Cambridge, stepped onto the balcony of Buckingham Palace Friday two hours after saying their "I do" - and they gave an audience estimated to be close to two billion people a royal moment to remember.

There were two kisses in total - and they were brief and pretty conservative pecks on the lips. It was a world away from William's parents' historic and slightly ostentatious embrace - but who can blame them getting a touch of stage fright? Body language expert Judi James said the William and Kate's kiss was elegant, modest and dignified, just like the couple. But there was no doubt about the body language of the royal couple's flower girl (pictured left). Take a look at the moment itself in the video below.
