Brigitte Macron’s sweet interaction with Kate Middleton has been decoded by a professional lip reader.

The royal family rolled out the welcome wagon for French president Emmanuel Macron and his wife Tuesday — complete with a horse-drawn carriage ride, traditional procession and a lavish State Banquet at Windsor Castle.

Fresh off the plane at RAF Northolt, the Macrons were greeted by the ever-stylish Prince and Princess of Wales.

After exchanging pleasantries, complete with handshakes, hugs and the customary French greeting of a double-cheek air kiss called “la bise” — Brigitte was spotted chatting away with the future queen.

“Thank you, thank you very much, thank you … it’s good to see you,” Brigitte said to Princess Catherine, 43, according to lip reader Jeremy Freeman.

Freedman told the Express that the French first lady told Middleton that it was “so good” to see her, adding, “You look great!”

Nearby, another heartwarming exchange was taking place between Macron, King Charles and Prince William.

As Macron warmly shook the monarch’s hand and kissed Queen Camilla’s, the French president then placed his hand on the king’s back.

Shortly after, lip reader Nicola Hickling told the Sun that Macron remarked on William’s tall stature, telling Charles, “He is incredibly tall.”

The king, who boasts a height of 5 feet, 10 inches, responded, “He is very tall. He’s six-foot-one, he is, ever so.”

It appears that William heard the pair’s exchange, chiming in, “Actually, I’m six-foot-three.”

Macron, who stands at 5 feet, 7 inches, cheekily quipped, “Unlike us, we’re short.”

Later in the day, Charles and Camilla hosted a lavish 160-person State Banquet, during which the king delivered a powerful tribute to William.

However, the king made no mention of his estranged youngest son, Prince Harry.

The Duke of Sussex quit royal life with his wife, Meghan Markle, in 2020 and moved to Montecito, Calif.

The “Spare” author, 40, recently told the BBC that he would “love a reconciliation” with his cancer-stricken father, though he claimed the king “won’t speak” to him.

“There’s no point continuing to fight anymore, life is precious,” the Invictus Games founder said, adding that he has since “forgiven” them for their many “disagreements.”
