Prince Harry, Meghan Markle, Prince William and Kate Middleton Join Royal Family at Remembrance Day Ceremony

Queen Elizabeth II, Prince Charles were there to honor those who lost their lives in war

Prince Harry, Meghan Markle, Prince William and Kate Middleton stepped out to honor those who lost their lives in war.

On Sunday, the royal fab four joined Queen Elizabeth II, Prince Charles and Camilla, Duchess of Cornwall at Remembrance Day, also known as Armistice Day, at the Cenotaph war memorial in London. Sunday's date, Nov. 11, marks 100 years since the end of World War I.

Wearing all black, the Queen, Kate and expecting Meghan also donned remembrance poppies, which is symbol honoring those who passed away in war. William and Harry both laid wreaths at the Cenotaph as a part of the Remembrance Day Commemorations.

Prince Charles, Prince Andrew and Prince Edward also laid wreaths during the ceremony as the Queen, the Duchess of Cambridge and the Duchess of Cornwall watched from the balcony of the Foreign and Commonwealth Office.

The Duchess of Sussex was close by the trio, watching from a balcony with judge Elke Büdenbender, who is the wife of Frank-Walter Steinmeier, the President of Germany.

On Saturday evening, Harry, Meghan, William and Kate all attended the annual Royal British Legion Festival of Remembrance at the Royal Albert Hall in London.

This reunion of the fab four followed two weeks after the Sunday Times reported that William and Harry are making plans to split their shared Kensington Palace household, meaning they'd create two separate courts with separate staffs "to reflect their increasingly different responsibilities."

Harry and Meghan recently returned from their first royal trip as a married couple. Following their arrival in Australia last month, it was announced that the couple is expecting their first child together.

"Their Royal Highnesses The Duke and Duchess of Sussex are very pleased to announce that The Duchess of Sussex is expecting a baby in the Spring of 2019," the palace said in a statement. "Their Royal Highnesses have appreciated all of the support they have received from people around the world since their wedding in May and are delighted to be able to share this happy news with the public."
