I’m a lip reader – what Kate Middleton sternly said to Prince Louis when he was spotted throwing a tantrum

MANY parents could relate to Kate Middleton having to calm down her excitable son Prince Louis at the Jubilee celebrations.

And now a lip reader has revealed exactly what the Duchess of Cambridge told her youngest child when he threatened to throw a tantrum in the royal box.

The four-year-old royal “stole the show” during nearly every one of his appearances over the four-day event - and the Jubilee Pageant was no exception.

Little Louis sat between Kate, 40, and his seven-year-old sister, Princess Charlotte, as they watched the show outside Buckingham Palace on Sunday.

Despite the extravagant parade, Louis was the centre of attention, pulling some very interesting facial expressions and even covering Kate’s mouth at one point.

Lipreading expert Jeremy Freeman told the exactly what Kate said to Louis when he started to appear grumpy.

Kate is said to have seen him picking his nose, and she put his hand down saying: “You have to.”

Louis then replied “I don’t want to”, before covering Kate’s mouth.

The mum-of-three then told her son: "I said no hands..."

She then pointed out the parade and told Louis to “look” before giving a wave.

In response, he blew a raspberry at his mum and stuck his tongue out, to which Kate responded: “Stop doing that.”

Royal fans had plenty to say after the young royal’s antics went viral on social media.

One fan posted on Twitter: ''Prince Louis being iconic as always.''

Another user said: "I love him. He’s amazing."

And a third joked: ";Not the hand on the nose.

"What is he? Dennis the Menace?!"

Louis had previously provided star-quality entertainment as he stood beside the Queen on the balcony of Buckingham Palace during Trooping the Colour.

The little royal covered his ears as the Red Arrow performed a stunning flyover.
