Prince Harry and Meghan Markle are not joining Kate Middleton and Prince William in Balmoral this weekend.

The Duke and Duchess of Cambridge flew to Balmoral on Thursday in a commercial flight. Prince William, Middleton, Prince George, Princess Charlotte and Prince Louis were spotted at the airport together.

However, according to a royal source, Prince Harry and Markle are not in a hurry to join the Cambridges and Queen Elizabeth II in Balmoral. The Duke and Duchess of Sussex will reportedly wait until next month before they travel to Scotland.

“Harry and Meghan won’t be going up at the same time as William and the cousins. They plan to go next month,” the source told Fabulous Digital.

Prince Harry is set to attend the Rugby League Challenge Cup Final at Wembley Stadium on Saturday. The Duke of Sussex has been a Patron of the Rugby Football League since December 2016. He will be presenting the Challenge Cup to the winners.

According to royal expert Robert Jobson of Daily Mail, Prince William and Middleton wanted to avoid Prince Harry and Markle after their tactless jibe at them. He was referring to Prince Harry’s statement saying that he only wanted to have two kids with Markle to save the planet. The royal commentator believes that it “irked the Cambridge, who already have three.”

If in case they would be in the Queen’s favorite home, the fab four would not have a hard time avoiding each other because according to Katie Nicholl of Vanity Fair, they will be staying in different cottages. The Duke and Duchess of Cambridge will be staying in their own cottage called Tam-na-Ghar in the round of the state. Meanwhile, Prince Harry and Markle will join Queen Elizabeth II and Prince Philip in the main house.

In related news, Prince William and Middleton’s commercial flight was deemed a PR stunt. According to royal commentator Marlene Koenig, the couple was likely advised to do it and Prince William believed that it was good for his family but it was a PR effort that backfired on them. Some also alleged that Prince William and Middleton were just trolling Prince Harry and Markle.
