Louis, who was born April 23 in London, will be officially baptized into the Church of England in the traditional christening ceremony on July 9 at the Chapel Royal in St. James's Palace, also in London.
Once the ceremony is complete, guests will attend a private reception at nearby ClarenceHouse where they will be served cake taken from a tier of William and Kate's wedding cake. Guy Pelly has been a longtime friend of the Kate and Will and Harry Aubrey-Fletcher went to Ludgrove School and Eton with Prince William.
Prince Louis was carried into the chapel by his beaming mother, wearing the handmade replica of the Royal Christening Robe, which in 2008 replaced the original which had been worn for all royal christenings since that of Queen Victoria's eldest daughter in 1841.
Lady Laura Meade is married to Prince William's close friend James, who is Princess Charlotte's godfather. At affair, the 34-year-old socialite donned a gorgeous baby blue dress to her nephew's outing that cut a similar style to the Alexander McQueen number her 36-year-old royal sis wore to her 2017 wedding. She's 92, you know.
Britain's Prince Harry, Duke of Sussex and Meghan, Duchess of Sussex leave after the christening.
