Royal No-Show
Kate appeared at the Trooping the Color event days before she planned to attend the Royal Ascot race meet.
Royal aides claimed the released program was an "error," and palace sources said the future Queen was "disappointed” to miss Royal Ascot, but “has to find the right balance as she fully returns to public facing duties."
However, some royal watchers believe the statement could be a cover-up to hide the true condition of the Princess of Wales.
Fans have pointed out Middleton has long been a regular at Royal Ascot – only missing the 2024 event as she underwent grueling treatment for an undisclosed form of cancer.
'Not Out Of The Woods Yet'
Insiders worry Middleton is currently grappling with the long-term effects of cancer treatment
As has previously been reported, courtiers have claimed the mother-of-three was diagnosed with ovarian cancer following a planned abdominal surgery in January 2024.

The Princess vanished from public view early last year - and revealed her shocking diagnosis in a March 2024 video, which captured the normally robust royal looking wan and sickly.
Now Middleton has disappeared again, insiders worry she's grappling with the effects of treatment – and my not be totally out of the woods.
Tipsters also say her husband and the rest of the royal family are inspired by her bravery, yet are deeply concerned as they're counting on Middleton to serve as a William’s Queen after the passing of King Charles, 76, who is also living with an undisclosed form of cancer believed to be incurable.
The burst blood vessel was said to be unrelated to Charles’ other health conditions.
Two days after missing Royal Ascot, Middleton released a heartfelt image of support of children’s hospices.
Courtiers say the statement indicates the survey is a cause hitting close to home for Middleton, enhancing the already pronounced empathy that may have driven her to resume public duties while still embroiled in her private struggles.
The plucky princess was on hand to hand to celebrate the king's birthday at Trooping the Color and attended the Order of the Garter service two days later.
A royal source said Middleton "knows she should not overdo things," adding, "Things have not been plain sailing."
Courtiers say the royal appears frustrated and fearful about her recent setback – and may secretly be worrying she may never fully recover.
