Prince Harry's girlfriend, actress Meghan Markle, will have to wait a little more to be invited to the royal family's private Christmas celebration. Kensington Palace had recently confirmed that the royal is dating the Suits actress.

Each year, the royal family joins Queen Elizabeth at Sandringham Estate in Norfolk, England. Markle's presence is in doubt as only close family members are invited for the function.

During an interview with ET, royal expert Katie Nicholl said: "My sources tell me that is not the case. [Harry] knows the rules of the royal family and he knows that until they get engaged, Meghan will not have a place around that Christmas dinner table."

"If you think about all those years that Prince William was courting Kate Middleton, she had to wait 10 years until she was invited to Sandringham. Harry and Meghan have only been dating for a few months. So, no, the queen has not stolen Christmas, and, no, Meghan Markle won't be at the Christmas table at Sandringham this year," Nicholl added.

Princess Diana's second son and Markle reportedly met when the royal was in Toronto, where the American TV legal drama is filmed, to promote the 2017 Invictus Games in May. Adding on, the dating rumours thickened when the 35-year-old American beauty was pictured wearing a bracelet almost identical to Prince Harry.

A source told People: "It's been an absolute fairy tale for Meghan. If she had to leave all that she's doing in order for the relationship to work, she would without hesitation. It's a very serious relationship and she wants a future with Harry."

If the couple's relationship works out, this will be second marriage for Meghan, who was previously married to Trevor Engleson in 2011. The two divorced in 2013.
