Duchess Kate's fake smile at Trooping the Colour raises concerns. "She's using this as a way to power through and do the best she can"

Last Friday, a new photo of Kate and William appeared on the official Instagram page. Kate Middleton announced that she would attend Trooping the Colour, King Charles III's birthday parade. This is her first public appearance since announcing her illness.

In her published post, she confessed that she would participate in several events this year but does not plan to return to work yet. As announced, she attended this year's parade.

Body language expert Darren Stanton analyzed her appearance on Business Insider. "Looking at the first photograph of Kate Middleton and Prince William heading to the ceremony together, Kate is using a masking smile. It's her game face,'" he explained.

The Duchess of Cambridge appeared at the annual parade for the king's birthday, one of the most important events for the British royal family. All eyes were on Kate, who made her first public appearance in over six months. She was last seen just after Christmas.

In January, she underwent abdominal surgery and withdrew from public life, which sparked a wave of speculation. The media was flooded with information about the sudden disappearance of the duchess. After three months of silence, Kate published a video in which she confessed that she was battling cancer.

Darren Stanton, a body language expert, analyzed the behaviour of the queen consort's wife during the parade.

— Looking at the first photograph of Kate Middleton and Prince William heading to the ceremony together, Kate is using a masking smile. It's her game face — he explained in an interview with Business Insider.

She's using this as a way to power through and do the best she can — he added.

In the photos from the royal carriage, the duchess is seen forcing a smile. She did not squint her eyes or the corners of her mouth, indicating that the expression was unnatural. According to the specialist, Middleton might not have felt very well, which is understandable during cancer treatment.

— Internally, she's feeling a sense of wanting to make people proud, but she is also feeling nervous - which is understandable — Darren Stanton said.

On a daily basis, the Duchess of Cambridge did not hold back her smiles and the royal "wave," a popular gesture among royal family members. During this year's parade, she did it only a few times.

— It makes her come across as quite stoic — he added.
