A new biography entitled Kate: The Future Queen has claimed that Kate Middleton changed her university choice to the same as William, after his decision was made public.

Royal writer Katie Nicholl, says it may not have been a coincidence that the couple met after all.

Speaking to Entertainment Wise the royal editor for the Daily Mail admitted it had been the most shocking revelation she uncovered when delving into the 31 year old's past.

"Probably the greatest and most surprising revelation was that she'd actually met Prince William while she was at school. She was at Marlborough, he was at Eton and they'd met when they were at Sixth Form through some mutual friends," she revealed.

"Through mutual friends Kate met William and that really put a new light on the situation because before then I'd thought they'd met at St Andrews, but they hadn't, they'd met at school."

She went on: "Then I'd discovered the very stunning revelation that she'd changed her university choice, she was meant to go to Edinburgh to study the history of art and she's changed to go to St Andrews when it was made public Prince William was going to go there to study the same course."

"The teachers I spoke to for the book and the friends I spoke to all said that it was very out of character. Usually Kate made her mind up and stuck to her decision, it was very rare for her to have a U-turn or a change of heart," she added.
