Princess of Wales and children show off sketching skills

These are definitely ones for the royal fridge door!

Catherine, the Princess of Wales, and her three children have all done drawings of each other.

However, Kensington Palace didn't reveal who drew each of the four pictures or who each of them is meant to be. What do you think?

Let us know in the comments below.

Do you think Prince William will do one too?

Prince George, Princess Charlotte and Prince Louis all put their artistic skills to the test with sketches published on social media.

And so has the Princess of Wales - our guess is that she drew the picture of Prince Louis taking a nap.

Catherine studied art at A Level, then history of art at St Andrews University in Scotland.

The four pictures were drawn to highlight an exhibition the princess recently launched at the National Portrait Gallery.

The exhibition encourages children to think about their relationships and feelings.

The princess had joined a class of five-year-olds going around it, encouraging children to portray themselves and to understand their own emotions.

"These skills are key throughout our lives, shaping who we are, how we manage our thoughts and emotions, how we communicate with and relate to others, and how we explore the world around us," said the message on social media, alongside the pictures.

"Drawing portraits with children can provide a moment of connection as you spend time looking at and focusing on one another, as well as being creative".
