It seems like Prince George and Princess Charlotte aren't the only Royals playing with colouring pencils.
Prince William revealed that his wife Kate Middleton is a fan of adult colouring books. The Duke of Cambridge made the surprising revelation while awarding illustrator Johanna Basford with Queen Elizabeth's honour for services to art and entrepreneurship.
“Prince William actually said that his wife likes to colour in Secret Garden, which was really sweet,” Basford told the Press Association after the OBE ceremony.
Kate Middleton is very health conscious as she's often seen out running, swimming, rowing and skiing and loves an almond milk smoothie.
