Meghan Markle is starting her holiday season with the British royal family! The Suits actress, who is engaged to Prince Harry, attended Queen Elizabeth's annual pre-Christmas lunch at Buckingham Palace on Wednesday, December 20, marking the first time the future royal will meet with the Queen's extended family. Harry, 33, was seen driving his bride-to-be toward the palace gates. The actress looked typically stylish in a chic ensemble by Self-Portrait. Meghan wore the Nightshade Midi Dress – and paired the outfit with dazzling diamond earrings by Birks.

Other members of the royal family seen arriving to the palace included Prince William and Kate Middleton, their children Prince George and Princess Charlotte as well as Harry's cousins Princess Eugenie  and her sister Princess Beatrice. Although Meghan has previously met the Queen, this is the first time she met The Duke and Duchess of Kent, their son Lord Frederick Windsor and his wife Sophie Winkleman. Lady Sarah Chatto, the Queen's niece, and Princess Alexandra, the Queen's cousin were also likely to have met the American actress. Meghan's appearance at the Buckingham Palace lunch is another indication of how quickly she has been accepted into the monarchy ahead of the May 19th wedding.

Last week, Kensington Palace confirmed that Meghan, 36, will join the Queen for Christmas at Sandringham. The actress will attend the traditional Christmas Day church service on the Queen's private estate in Norfolk. "You can expect to see the Duke and Duchess of Cambridge, Prince Harry and Ms. Markle at Sandringham on Christmas Day," a Kensington Palace spokesman said. Meghan and Harry have already gotten in the Christmas spirit by stopping in to his grandmother's staff holiday party as well as being among the guests at the Kensington Palace annual staff Christmas party, which was held at Beach Blanket Babylon in Notting Hill.

Meghan's invitation marks a break in tradition for the royals. The Duchess of Cambridge was not invited to join Prince William for Christmas in 2010, despite announcing their engagement a month before. England rugby player Mike Tindall was also not invited during his engagement to Princess Anne's daughter Zara Phillips, also in 2010.
