Prince Louis’s adorable “fixation” with Princess Charlotte’s jewellery has been revealed by his dad Prince William.

During a walkabout in Llanelli, South Wales, in September, William revealed to 10-year-old Ruby Davies that his youngest son “tries to steal all his sister’s bits”.

Ruby kindly gifted William with a book of postcards written by students from Swiss Valley Community Primary School.

She also gave the heir to the throne some friendship bracelets for Louis, Princess Charlotte, nine, and Prince George, 11.

The 42-year-old then told Ruby: “Thank you so much, Ruby. They’re going to love those. You’ll see them out and about.

“I’ll keep them away from Louis because he’ll try and steal all his sister’s bits.”

As well as speaking to Ruby about his children, he also told her that he had seen her viral video from winning in the recital category at Eisteddfod, an annual competition in Wales.

William added: “I’ve watched your video a few times, Ruby. You did brilliantly, and you don’t seem nervous about performing on stage at all.”

Charlotte and George were previously spotted wearing Taylor Swift-inspired friendship bracelets to attend the US hit singer’s concert in London back in June.

The two young royals attended the Eras Tour with dad William – whilst Louis is thought to have stayed at home with the Princess of Wales.

Charlotte – who is said to be a huge fan of Taylor Swift – was also spotted wearing a friendship bracelet at Wimbledon earlier this year. Big brother George sported one in his official 11th birthday portrait in July.
