A source tells PEOPLE that the Duke and Duchess of Sussex have not received an invitation to this year’s royal Christmas gathering at Sandringham. The couple, who are expected to spend the holidays in the U.S., haven’t taken part in Christmas with the royal family since 2018, the year they married.

As expected by many, a source confirmed Prince Harry, 40, and Meghan Markle, 43, have not been invited to spend Christmas with the royal family at Sandringham in Norfolk. Instead, the duo could be set to "totally snub" the monarchy and spend the festive season with another branch of their extended families.

The last time the Duke and Duchess of Sussex spent Christmas at Sandringham was in 2018, the year they tied the knot in the UK.

The Duke and Duchess of Sussex have not spent Christmas at the Sandringham Estate since 2018, two years before they quit the Royal Family and moved to the UK. But it is understood the Sussex couple will spend their holidays in Montecito, California, where they reside with their two children, Prince Archie and Princess Lilibet, People reports.

Princess Diana's issues with the Royal Family's Christmas celebrations began right away with her first royal Christmas in 1981, according to her biographer Andrew Morton, author of Diana: Her True Story in Her Own Words.

Kate Middleton, Prince William, and their children will join King Charles at Sandringham for a deeply emotional Christmas, following health challenges.

The Duke of Sussex appeared in a knockabout comedy sketch earlier this month - one which showed the world that the 'old' Harry still exists.

Prince Harry and Meghan Markle may be hoping that someday soon the fates will allow they be together with the royal family at Christmas, according to reports. The holiday is looking to be “bittersweet” for the couple as they are “missing” spending the most wonderful time of year with the royal family,

The royal family will reportedly spend another holiday season apart from Prince Harry and Meghan Markle. According to a source familiar with the monarch's Christmas plans who spoke to People, King Charles is not inviting the Duke and Duchess of Sussex to this year's royal Christmas gathering at Sandringham.

Royal correspondent Rhiannon Mills claimed Prince Harry told her he'd 'love to move away' during a chat in 2015 prior to him and Meghan Markle leaving the royal family
