A lip reader has uncovered what cheeky Prince Louis asked his dad during the VE Day parade — while Kate was spotted sharing a sweet comment with Princess Charlotte.

Seven-year-old Louis was seated next to his father, Prince William, and couldn’t help but show off some playful dance moves, swaying his shoulders as he looked out at the crowd.

At one point, he was seen gently brushing raindrops from William’s shoulder.

Prince William turned to his son and gave him a light tap on the leg.

According to lip reading expert Nicola Hickling, speaking to The Sun, William told Louis: “Look at this I think it’s going to be quite wet today.”

Louis then asked his dad: “Wasn’t this supposed to be fun?” to which William responded, “It is son.”

The future king also reassured him: “You will never forget this,” before giving a brief explanation of the parade.

“They will come along here, and then go towards there, and then we will make our way back,” he said, adding, “It’s not going to be long and I want you to be taking an interest.”

Meanwhile, Prince George, 11, interjected, saying: “I’ve got something in my eye.”

Princess Kate, too, shared a touching moment with her daughter Charlotte, 10. The mum-of-three was seen telling her: “Doesn’t papa look smart today.”

Fellow lip reader Jacqui Press offered additional insight into a brief exchange between Queen Camilla and a veteran.

The Queen was heard saying: “Ooh it’s much warmer inside it’s cold are you comfortable?”

To which the veteran replied: “Yes I am thank you so much.”

Another gentleman was overheard saying to Princess Kate: “Lovely to see you with all your family.”

As Kate showed some photos to her children, she pointed something out to Charlotte and said: “Look at his uniform!”
