Kate Middleton accidentally let slip ‘adorable’ nickname for Prince Louis

Kate Middleton once accidentally revealed the wholesome nickname she has for Prince Louis during a royal engagement.

Prince Louis could arguably be one of the UK’s most adored royals.

Between his cheeky little grin and doing silly things in front of the cameras - just like any six-year-old would do - he seems to be totally bewildered by the amount of attention his family gets.

He never fails to entertain the crowds, whilst probably stressing out his mum - the Princess of Wales - in the meantime. And one of his royal engagements last year made no exception.

The Wales family took part in the Big Help Out at 3rd Upton Scouts Hut in Slough on 8 May, 2023 - shortly after King Charles' coronation - to help renovate the building.

An adorable clip from the day shows Kate and a scout member helping Louis prepare a S’more – a sandwich made from a melted marshmallow between biscuits – which he wasted no time eating.

But the mum-of-three was heard affectionately calling her youngest 'Lou-Bugs' as she told him to put his wooden stick used to toast a marshmallow into the fire.

Louis definitely enjoyed his snack as he licked the marshmallow off his fingers while eating the delicious s’more.

Dad Prince William could be heard making a joke about his son’s apparent sweet tooth, telling the crowd: “You won’t hear a peep out of him now,” as everyone chuckled.

In more recent royal news, Kate Middleton gave the nation a much-needed health update after she revealed she was undergoing treatment for cancer back in March.

In a statement posted on social media on 14 June, the 42-year-old opened up about her health.

She wrote: "I have been blown away by all the kind messages of support and encouragement over the last couple of months.

"It really has made the world of difference to William and me and has helped us both through some of the harder times.

"I am making good progress, but as anyone going through chemotherapy will know, there are good days and bad days.

"On those bad days you feel weak, tired and you have to give in to your body resting.

"But on the good days, when you feel stronger, you want to make the most of feeling well. My treatment is ongoing and will be for a few more months.

"On the days I feel well enough, it is a joy to engage with school life, spend personal time on the things that give me energy and positivity, as well as starting to do a little work from home."
