As Prince William and Princess Catherine stepped out for a major public event, a brief exchange between the couple was captured on video.
Now, a lip reader claims to have decoded their private conversation—offering a rare glimpse into their candid moment.
Princess Catherine drew attention as she arrived at Westminster Abbey for the annual Commonwealth Day Service on March 10, 2025. Dressed in a striking red outfit, she completed the look with matching shoes, a hat, and a clutch. She attended the event alongside her husband, Prince William.

As expected, body language experts closely observed Catherine’s demeanor. Every gesture and expression was analyzed as she moved under the watchful gaze of the public.
One moment, in particular, caught the attention of a lip reader. A brief exchange between Catherine and William as they approached the venue quickly circulated on social media.
In a video clip circulating on social media, Catherine appears to turn toward someone on her left and say, “Thanks.” She then faces Prince William and comments on the celebration, reportedly saying, “So lovely.” William, ever composed, is said to have responded with a simple remark, “Not bad, right?”
The exchange, though subtle, has sparked interest among royal watchers, offering a glimpse into the couple’s private conversations during the high-profile event. As the Commonwealth Day celebrations unfolded, the royal couple remained at the center of attention, their presence reinforcing their role within the monarchy.
Princess Catherine’s appearance at the 2025 Commonwealth Day Service carried special significance. Just a year earlier, she had been absent from the same event due to health concerns, leaving Prince William to attend alone. Her absence in 2024 raised questions among royal watchers, as speculation grew about her condition.

In January 2024, a statement from Kensington Palace revealed that Catherine had undergone major abdominal surgery. While the procedure was successful, doctors advised a recovery period of up to two weeks in the hospital, followed by extended rest at home.
The palace noted that she was unlikely to return to public duties until after Easter, emphasizing her wish for privacy, particularly for the sake of her children.

A few months later, Catherine addressed the public directly in a heartfelt video message. “In January, I underwent major abdominal surgery in London, and at the time, it was thought that my condition was non-cancerous,” she explained.
“The surgery was successful. However, tests after the operation found cancer had been present.” She described the diagnosis as a “huge shock” and shared that she was undergoing preventative chemotherapy.
By September 2024, Catherine had completed treatment and expressed relief at reaching the milestone. “I cannot tell you what a relief it is to have finally completed my chemotherapy treatment,” she said.
In January 2025, she took to social media to share that she was in remission. “It is a relief to now be in remission, and I remain focused on recovery,” she wrote. She also thanked The Royal Marsden for her care, adding, “My heartfelt thanks go to all those who have quietly walked alongside William and me as we have navigated everything.”
Her return to Westminster Abbey for the 2025 Commonwealth Day Service was more than just a royal engagement. It marked a personal triumph—a symbol of resilience and strength after a year of uncertainty.
