The Duchess of Cambridge confessed that she felt shy when she was first introduced to Prince William at university in 2001.
The pair both met at the University of St Andrews in Scotland.
Kate said: “I actually went bright red when I met you and scuttled off feeling very shy about meeting you.
“William wasn’t there for quite a bit of the time initially, he wasn’t there from Fresher’s Week, so it did take a bit of time for us to get to know each other.
“But we did become very close friends from quite early on.”
However, her husband revealed he couldn’t remember their first meeting as vividly Kate in the couple’s recently resurfaced engagement interview from 2010.
William said he would have to “wrack his brains” to recall when he first met his wife, whom he has three children with.
Kate and William began dating during their university years. However, they took a brief split, which they have both described in a previous interview in positive terms.
The break is said to have taken place over the Christmas period in 2006.
William said: “We did split up for a bit.
“We were both very young, it was at university and we were both finding ourselves and being different characters and stuff.
“It was very much trying to find our own way and we were growing up.
“It was just a bit of space. It worked out for the better.”
The Duchess added: “At the time I wasn’t very happy about it but actually it made me a stronger person.
“You find out things about yourself that maybe you hadn’t realised.
“I think you can get quite consumed by a relationship when you’re younger.
“I really valued that time, for me as well, although I didn’t think it at the time.”
Both the Duchess and Prince studied the history of art at university.
William’s decision to attend St Andrews’ University went against Royal convention, as the Royal Family members traditionally attend Oxford or Cambridge.
The two became friends early on in their relationship before marrying in 2011.
