Kate Middleton coloring hobby revealed by Prince William

When her royal duties get a little too much to bear, the Duchess of Cambridge, née Kate Middleton, relaxes by filling the boxes with the right colors.

You guessed it, George and Charlotte’s mother is a fan of coloring-in books.

William made the revelation on Tuesday, while awarding illustrator Johanna Basford the OBE for services to art and entrepreneurship at Buckingham Palace.

“Prince William actually said that his wife likes to color in Secret Garden, which was really sweet,” Basford told the Press Association after the ceremony. [via The Telegraph]

“I’m working on a new book just now and it’s set in a castle, funnily enough, so I will definitely try to remember everything. I’m sure little snippets of today will feature in the book.”

Kate, whose artistic sensibility is also evident in the practice of photography, has delighted royal fans in the past with photos of her children, Princess Charlotte and Prince George.
