A communications mix-up between the British Ministry of Defense and the Royal Family resulted in false reports that Princess of Wales Kate Middleton would lead a major troop review parade in June, according to Fox News.

Middleton, the wife of the future king Prince William, who has been quietly recovering from an unspecified abdominal surgery in January, was briefly listed on the British military's official website as the lead official for the "Trooping the Colour - The Colonel's Review" parade scheduled for June 8 along The Mall near Buckingham Palace.

The future queen's name was shortly thereafter removed from the website for the second of the three "Trooping the Colour" parades on three consecutive weekends in June that are intended to annually honor the British monarch's birthday -- even though King Charles III's actual birthday is in November.

Middleton's name removed from troop review; King Charles still listed

According to Fox News, the British Army failed to obtain prior approval from Kensington Palace, which manages the offices of the Prince and Princess of Wales, before listing Princess Kate as the lead reviewer of the second Trooping the Colour parade on June 8.

Yet, while Middleton's name has now been removed from the website, King Charles is still listed as the lead official for the main Trooping the Colour - The King's Birthday Parade event scheduled for June 15.

That said, given the king's cancer diagnosis last month and despite his efforts to continue performing most of his official duties while receiving unspecified treatments, there is some uncertainty that he will be in attendance at that annual event in his honor.

Kate is "doing well" in her recovery, palace says

USA Today reported last week that there has been widespread, and at times wild, speculation on social media about the unknown health status of Princess Kate, whose last formal public appearance was on Christmas Day before her mid-January abdominal surgery.

An initial statement from Kensington Palace revealed that Middleton would be hospitalized for up to two weeks, after which she would continue her recovery from home, that she had requested privacy during that recovery period, that she wasn't expected to return to her public duties until after Easter, and that updates would only be provided if there was "significant new information" that needed to be shared with the public.

In response to all of the online speculation about her current health status and when she might return, however, Kensington Palace told ABC News last week that Princess Kate was "doing well" in her recovery but stated, "Kensington Palace made it clear in January the timelines of the Princess' recovery and we'd only be providing significant updates. That guidance stands."

Online speculation fueled by public's "uncertainty" about health of senior Royal Family members

It appears that the statement from Kensington Palace last week failed to quash the speculation about Princess Kate's health and recovery, according to People magazine, as talk of "turmoil" in the British Royal Family continues amid her absence and King Charles' recent drawback from some public appearances while dealing with his cancer diagnosis.

"Everybody feels unsettled by uncertainty, and there is too much uncertainty that is surrounding the monarchy right now," royal biographer Sally Bedell Smith told the outlet. "Queen Elizabeth used to say, 'I need to be seen to be believed.' It is important for Charles and his reign for the public to know a little bit more."

"The monarchy needs to be that anchor in times of trouble, and any sense of instability, which is inevitable when you have two of the key players out of action, is understandable," she added.

As for Prince William, who initially stepped back from his public duties to help care for his recovering wife and their three young children, he recently released a statement through a spokesperson to address the mounting speculation about his family.

That statement simply said of the future king, "His focus is on his work and not on social media."
