The Princess of Wales has a sweet nickname for her youngest son, Prince Louis, who is often seen getting up to adorable antics.

In Kate’s recent video, she announced she had finished her chemotherapy treatment and that ‘doing what I can to stay cancer free’ was now her main focus.

The uplifting message featured in wholesome footage of the Princess with her family.

At the very start of the video Kate, 42, is walking through a woodland area with Prince William, 42, Prince George, 11, Princess Charlotte, nine, and Prince Louis, six.

The Princess of Wales can be heard affectionately calling out to her youngest, ‘Lou-bugs, you lead the way!’

Louis walks confidently on ahead of his family and repeatedly throws a ball up to catch while his siblings and parents follow behind.

Later on in the video, Kate is shown pushing Louis on a swing as he stands up enthusiastically.

In another clip, Louis sits next to his mother before leaning in to the camera saying ‘hello, hello’.

Kate was first heard using the sweet nickname, ‘Lou-bugs’, for her youngest son in May last year.

William, Kate, George, Charlotte and Louis attended The Big Help Out event and helped to renovate a Scout hut in Slough.

Louis, who was five years old at the time, didn’t hesitate to get stuck in during his first public engagement and shovelled sand into a wheelbarrow while Kate stood nearby encouraging him.

He then pushed the wheelbarrow over to other volunteers who were helping to build a path.

The Princess of Wales praised Louis saying, ‘Well done, good job, Lou-bug.’

Kate used the adorable nickname again later on when the family joined others around a fire to toast marshmallows and make s’mores.

Helping Louis to put his sweet treat onto a stick and then handing him an empty skewer to throw away, she told her youngest, ‘Pop that in the fire, Lou-bug’.

Elsewhere, she was heard lovingly calling Louis ‘poppet’ as he eagerly grabbed a brush to help paint his hand print on the wall inside the scout hut.

Kate encouraged Louis to cover her hand with yellow paint saying, ‘Hey poppet.’

The young prince then helped his mother to place her hand on the wall, the Princess of Wales then smiled, saying ‘Ready, steady, go. Good job!’

He then covered his own hand with blue paint and eagerly put it against the wall.

Kate and William have been known to use sweet nicknames for their children previously.

Charlotte’s adorable moniker was revealed in a video released by Kensington Palace on Instagram, showing the family-of-five at the Chelsea Flower Show in 2019.

While the three children are seen running around enjoying the outdoors – at one point William called out for his daughter, but instead of calling her Charlotte, he called out for ‘Mignonette’.

Mignonette is a French word which is said to mean ‘small, sweet, and delicate’ or ‘cute’.

The Princess of Wales opts for a simple yet classic nickname for her daughter, having previously been known to call her ‘Lottie’.
