Prince Harry and Meghan Markle just announced their decision to celebrate Christmas in the United States. This way, the royal couple could spend time with the Duchess of Sussex’s mom, Doria Ragland, who is residing in Los Angeles.

A statement was released announcing the royal couple’s plans earlier this week. And it was confirmed that Queen Elizabeth gave Prince Harry and Markle the go-signal to push through with their trip.

But a source recently told Us Weekly that there’s another reason why the Duke and Duchess of Sussex have opted to celebrate the holidays away from the royal family this year. And it has something to do with Prince William and Prince Harry’s feud.

Since the royal siblings are not on good terms, Prince Harry and Markle want to avoid any form of stress during the holiday season. Instead of spending Christmas in Sandringham and crossing paths with the Duke of Cambridge, they have decided to celebrate the special occasion elsewhere.

“Harry and Meghan are having a small Christmas with just immediate family instead of spending it at Sandringham,” the source said. “The rift between William and Harry is one of the main reasons behind their decision. As it’s Archie’s first Christmas, they want it to be super special. It’ll be just Doria and the three of them,” the source added.

The insider went on to say that Prince Harry and Markle want to prioritize their family this time around. As such, after spending Christmas in Sandringham two years in a row, they have decided to go to the United States to be with Markle’s mom.

As of late, it is still unclear up to when the Sussexes will be in the U.S. But, a royal correspondent recently said that the royal couple deserves a time out from all of the criticisms that they have received.

Throughout the past year, Markle and Prince Harry have been pitted against Prince William and Middleton. They have also been slammed for taking a private jet during their summer vacation. And they were also criticized for filing a lawsuit against a handful of publications.
