Just one day after attending the christening of Prince Louis, Kate Middleton and Prince William, Prince Harry and Meghan Markle were pictured arriving for a service to mark the centenary of the Royal Air Force at Westminster Abbey in central London.
After the ceremony had taken place, the family emerged from the Chapel Royal, with Charlotte carefully clutching the order of service under her arm and sweetly waving to the photographers again. As after George and Charlotte's baptisms, guests will be served slices of the duke and duchess's wedding cake.
Prince Louis, the third child of the Duke and Duchess of Cambridge, was baptized on Monday at the Chapel Royal at St. James's Palace. The Duchess of Cambridge was seemingly giving fans clues about Prince Louis' gender, rocking shades of blue to nearly every royal appearance ahead of his arrival in April.
