The 34-year-old Swedish royal has dyslexia, like her brother Prince Carl Philip and her elder sister Princess Victoria, but has revealed she has been spending her time in London writing her first-ever book.

She told the Swedish newspaper Expressen: "I'm working on a separate project, my book project. It's a children's book. You'll see what is is soon. At the moment all I can say that it will be fun."

And Princess Madeleine - who has two young children with her financier husband Chris O'Neill - revealed books are playing an increasingly prominent role in her life.

The glamorous royal, whose daughter Princess Leonore turns three on February 20, said: "Previously Leonore had not really had the patience, but now [she wants] more and more books, which is great fun. It is a cosy moment you have together."

Meanwhile, Princess Madeleine also previously said she loves her 20-month-old son Prince Nicolas "to the moon and back".

In a heartfelt birthday message for her son in 2016, she wrote: "Happy Birthday Nicolas! You are our sweetheart and we love you to the moon and back."

Princess Madeleine and her husband - who tied the knot in 2013 - have been living in London since 2015, although they still make frequent trips back to Sweden to attend special occasions.
