Sarah 'Fergie' Ferguson has taken to Instagram and revealed that she and daughters Princess Beatrice and Eugenie have broke royal protocol.
Sharing to the social media platform, Fergie posted a picture of an artwork by 'Teddy M', and revealed that all three of the royals had signed the piece.
For the royal family - autographs are a big no-no!
However, the behaviour of Fergie, Beatrice and Eugenie might fly with Her Majesty, as it's all in the name of a good cause.
The original painting, dubbed 'Royal Love', was created in 2016 by GQ Magazine, with the artist stating: 'We painted outdoors on the lawn, kneeling over the artwork and it was such a relaxed experience.
'When you look at the painting, you will see three distinct forms of handwriting. Beatrice on the bottom left, Eugenie bottom right and the Duchess across the top.'
Adding: 'And the name of the painting, 'Royal Love' seemed obvious to me and the Duchess quickly approved.'
The painting was auctioned at the Masterpiece Fair in 2016, and sold for £15,000 (AU$27,000), with all the money going to the charity, Children in Crisis.
Recently, Teddy M has teamed up with Ed Sheeran for fundraising efforts, with his art guitars raising thousands of dollars for a number of charities.
