Prince William, Kate Middleton, Prince Harry and Meghan Markle had a shocking showdown at a recent royal event.

On Saturday, the fab four shruggedoff the rumors about their falling-out when they stood together on the Buckingham Palace balcony for Trooping the Colour. However, according to New Idea, “Not all was as it seemed and that their unite’s front was simply just for show.”

Royal insiders told the publication that the Cambridges and Sussexes have reached a breaking point after Prince Harry and Markle abruptly pulled out of the Royal Foundation, the charity that the royal trio founded together in 2009, last week.

“You could cut the tension with a knife,” an insider told the publication before adding that “away from the cameras, Harry and Meghan barely uttered two words to William and Kate.”

Trooping the Colour is a centuries-old tradition celebrating the monarch’s official birthday. Now that Queen Elizabeth II is already 93 years old, every year she celebrates her birthday is so precious and important, so the fab four couldn’t miss it. Also, the Queen holds the whole thing together.

“Neither family wants to let the Queen down so they will appear together in public, as they did as Trooping, and say the right things. But away from prying eyes, they are seeing less and less of each other,” the source continued.

At Trooping the Colour, Middleton, Markle, Prince Harry and Camilla Parker Bowles shared a carriage ride. According to body language expert Judi James, Middleton was showing signs of tension and lack of “relaxation.”

Middleton has always shared a carriage ride with the Duchess of Cornwall for the said event since she first joined them in 2011.

Prince William and Prince Charles both joined the parade in horseback with Prince Andrew, Princess Anne and Prince Edward, since all of them have ceremonial roles as Colonels of the Household Division.

The Duke of Cambridge is the Colonel of the Irish Guards while Prince Charles is the Colonel of the Welsh Guards. Thus, Middleton and Camilla always sit beside each other during the Trooping the Colour parade.

In related news, royal historian Anna Whitelock warned the royal family about Markle’s growing popularity. According to her, after delivering baby Archie, Markle “holds all the cards now.”
