The Duchess of Cambridge is the centre of attention whenever she goes.
Whether it's an official engagement or popping to the supermarket, Kate turns heads and rarely manages to go about her day-to-day unnoticed.
But according to a new book about the royal family, the busy mum-of-three has a little trick to "nourish her inner life".
Journalist and friend of Princess Diana Tina Brown's The Palace Papers, which goes on sale next month, claims that Kate goes for secret 8am visits to London's museums and art galleries, reports the Daily Mail.
She claims that she was spotted at a Hockney exhibition at the Royal Academy by a stunned member of the public.
She reportedly told him: "I miss my history of art,’ she told him. ‘It’s what I do to get my fix."
Kate studied the subject at the University of St Andrew's, where she met Prince William, graduating in 2005 with a 2:1.
She's a talented artist and is particularly fond of sketching.
For the wedding of her sister, Pippa Middleton, she drew St Mark's Church (where the ceremony was held) for the front cover of the order of service.
James Matthews, Pippa's husband and Kate's brother-in-law, praised the drawing in his wedding speech, saying "to Pippa’s sister Kate, such ability – a beautiful drawing of St Mark’s church in the order of service."
Art is a passion Kate's brought into her royal work especially when it comes to her patronages.
She put her degree to good use when she selected photos for the National Gallery's Victorian Giants: The birth of art photography exhibition back in 2018.
She also wrote the captions to go alongside each picture and the foreword to the exhibition catalogue.
Kate is also a talented photographer and takes the majority of her family's official photos.
Just today she released her latest collection of snaps, four beautiful images of her youngest son Prince Louis to mark his fourth birthday.
The pictures show the little royal playing bare foot on the beach with a cricket ball.
But it seems she has another creative hobby - knitting, although she's confessed she's "really bad" at it.
Kate's revealed she was trying her hand at knitting way back in 2013 when she was pregnant with Prince George.
According to Hello!, she told a group of royal fans while visiting Glasgow: "I've been trying to knit and I'm really bad. I should be asking for tips!"
She admitted that her attempts to knit George a jumper had gone slightly awry, telling the group: "I tried knitting when I first had George. I tried to knit him a very special jumper, but I got halfway down and it splattered. It's such an amazing skill."
