The 'Suits' actress is reportedly set to spend the festive period with her fiancé Prince Harry and her future brother and sister-in-law and their children, Prince George, four, and Princess Charlotte, two.

A source told Us Weekly magazine: "They'll be William and Kate's guests and travel back and forth with them."

It is believed the engaged couple will join the rest of the family on Christmas Eve with Queen Elizabeth at Sandringham and then will stay with the Duke and Duchess of Cambridge at their home of Amner Hall in Norfolk.

They are expected to start their Christmas Day with a traditional English breakfast before going to attend the church service at St. Mary Magdalene Church, followed by some Christmas lunch. Later, they will watch the Queen's speech and when the Princes have to go and partake in their royal duties on Boxing Day, Meghan and Catherine - who is expecting her third child - will keep each other company at home.

Meanwhile, it had previously been reported that Meghan could be the first royal fiancée to spend Christmas with Queen Elizabeth before the royal couple jet back to the United States to spend New Year's with Meghan's family.

It is said that usually the royal family only accept married couples to join them for Christmas but are making an exception this year for Prince Harry and Meghan.
