The lunch was attended by over 50 members of the British royal family, People reports, including Harry's father, Prince Charles, his wife, Camilla, Princess Eugenie and Princess Beatrice, along with tots Prince George and Princess Charlotte.

Both Harry and William drove to the festive event. William arrived in a black Range Rover with Kate, George, Charlotte and their nanny, Maria Turrion Borrallo, while Harry drove a Land Rover Discovery separately with Meghan.

When she was leaving Buckingham Palace on Wednesday, Markle flashed her gorgeous engagement ring, which her fiancé designed himself. The star appeared to be wearing a high-collared black-and-white ensemble that featured a detailed overlay complete with floral cutouts. The rest of her ensemble wasn't visible.

The former "Suits" actress had already met Harry's grandmother the Queen on multiple occasions, but Wednesday was surely her first time meeting a handful of other important people in his life.

The outing comes just before the core members of the British royal family head to Queen Elizabeth's Sandringham estate to celebrate Christmas together. Markle will be in attendance for the intimate gathering, which will be a break in tradition for the family, which normally only invites significant others that have officially married into the clan.

Markle is expected to spend Christmas morning with Will and Kate and their two children, as George and Charlotte open stockings from Santa.

Harry and Meghan are set to get married at Windsor Castle on May 19, 2018. They announced their engagement last month to much fanfare.
