Kate Middleton and King Charles share a laugh during first public appearance together since cancer diagnoses

Kate Middleton shared a sweet moment with her father-in-law, King Charles III, on the Buckingham Palace balcony during Trooping the Colour Saturday.

In a clip circulating online, the Princess of Wales could be seen giggling as she briefly chatted with the monarch, who laughed in response.

“Look at the natural closeness and warmth between King Charles and the Princess of Wales,” a social media user wrote via X Saturday.

“He adores her. Princess Catherine is like a daughter to him. We’re so lucky to have her in our #RoyalFamily Britain’s future Queen.”

The two royals are known to have always had a good relationship but may have grown even closer in the last few months as they both battle cancer.

In March, Middleton and Charles reportedly sat down for a private lunch to discuss their “common health experience.”

A month prior, Buckingham Palace announced the King, 75, had been diagnosed with cancer following a “routine hospital procedure for benign prostate enlargement.”

He then temporarily stepped back from royal duties to concentrate on treatment.

Royal fans were shocked when Middleton, 42, announced in March that she, too, had been diagnosed with cancer after undergoing abdominal surgery.

In an emotional video, the princess confessed that the health issue “came as a huge shock.”

After spending some months privately undergoing chemotherapy, Middleton made her first pubic comeback Saturday to participate in the King’s annual birthday parade.

A Buckingham Palace spokesperson told Page Six Friday that Charles was “delighted” the princess was able to attend and was “looking forward to all elements of the day.”

On the morning of the parade, Middleton shared a tender moment with her 9-year-old daughter, Princess Charlotte, in which she was seen gently stroking the little girl’s hair.

She then happily rode in a carriage with all three of her kids, which also include Prince George, 10, and Prince Louis, 6, before posing with the other royal family members at the Buckingham Palace balcony.
