Prince William and Kate Middleton makes for one of the greatest love stories of our time, and probably in the most obvious news of the day, he allegedly fell for her because of her "perfect smile".
The Duchess of Cambridge, who was joined by her sister Pippa Middleton at the Wimbledon's Mens Final yesterday to watch Roger Federer beat Andy Murray, met Prince William when they were both studying at the University of St. Andrews.
Now a behavioural expert Judi James has reportedly revealed what exactly it was that caught Wills' eye.
"I think William was drawn to her because she has the perfect smile; bright teeth, dimples, round rosy cheeks, and in public her body language gives nothing away," James revealed. "She also added that Kate was more like the Queen than she was to his late mother Princess Diana, which is why Kate fits into the Royal family well.
"Just like the Queen, whose body does not move, and unlike Princess Diana who was very easy to read," James explained. "Usually with the Royal Family you have to watch them for a significant amount of time before they show any 'leakage' as we call it."
Since become the Duchess of Cambridge after marrying William in April 2011 at Westminster Abbey, Kate has become a hit with the public.
"Kate's smile and her ability to hold it is a major asset. Normally it's impossible to hold a genuine smile for 10 minutes straight," James told the Sunday Express. "I've tried and couldn't. She's practised a lot."
