The royal foursome joined Queen Elizabeth and Prince Charles at the Commonwealth Day service at Westminster Abbey in London on Monday, marking the Duke and Duchess of Sussex's final engagement as senior members of the royal family. Neither the Sussexes nor Cambridges walked in the Queen's procession for the service, though they were seen greeting each other at their seats during the ceremony. In video footage from the event, Meghan could be seen smiling and waving, mouthing "hello" to Prince William and Kate Middleton. The annual Commonwealth service is an event to celebrate the Commonwealth nations of the U.K. and their shared democracy. Following the event, Meghan and Harry are expected to return to Canada, where they'll begin their new life after officially ending their royal duties on March 31.
