How cute.

Kate Middleton revealed today that her nickname at junior school was 'Squeak' - after the school guinea pig.

Kate was visiting her prep school, St Andrew's in Pangbourne, Berks, which she attended from the age of four to 13.

She was dressed up for the occasion in a never-before seen tailor made tartan coat-dress by Alexander McQueen, the same design house that made her wedding dress. She was there to open a new astroturf sports field.

Kate said in a speech: "I absolutely loved my time here, they were some of my happiest years, which makes it so incredibly special to be here today.

“In fact, I enjoyed it so much that when I had to leave, I told my mother that I was going to come back to be a teacher.

“While that didn’t quite happen, I was thrilled to have been asked back today on St. Andrew's Day.

"It was while I was here at school that I realised my love of sport.

“Sport has been a huge part of my life, and I feel incredibly grateful for the opportunities I had to get outside and play in such wonderful open spaces - though sadly there was nothing quite as glamorous as this in my time.

"I hope that you all enjoy playing sport here as much as I used to, and make the most of these incredible facilities."
