Britain's Prince George has been official baptised.
The Duke and Duchess of Cambridge have emerged from the Chapel Royal at St James' Palace with the future king of England following the ceremony.
Catherine wore a striking cream Alexander McQueen coatdress with a ruffle down the front and a matching pillbox hat, while William went for a simple navy blue suit with pale blue tie.
George wore a replica of the Royal Christening Robe, made by the queen's dressmaker Angela Kelly. A version of the piece has been worn by every royal baby who has been christened since 1841.
Only 24 people were invited to the ceremony, which bucked tradition as such christenings are usually held at Buckingham Palace.
There were just five members of the senior royal family invited today, Queen Elizabeth II, Prince Philip, Prince Charles, the Duchess of Cornwall and Prince Harry. Catherine's mother and father Carole and Michael and her brother James and sister Pippa were also in attendance.
Also there were the seven godparents who were announced earlier today. William's cousin Zara Phillips has been chosen along with Oliver Baker, who attended the University of St. Andrews with the couple. William's late mother Princess Diana's close friend Julia Samuel was bestowed the honour too.
Godmother Emilia Jardine-Paterson attended Marlborough College with the duchess, while godfather Earl Hugh Grosvenor is the son of the Duke of Westminster.
Lastly there is Jamie Lowther-Pinkerton, the couple's private secretary, and William's childhood friend William van Cutsem.
The Archbishop of Canterbury, the Most Rev Justin Welby performed the baptism, using the Lily Font and water from the River Jordan.
"As a nation we're celebrating the birth of someone who in due course will be the head of state," the archbishop told British newspaper The Daily Mail today.
"That's extraordinary. It gives you this sense of forward looking, of the forwardness of history as well as the backwardness of history, and what a gift to have this new life and to look forward."
Once the ceremony finished, guests were treated to a private tea courtesy of Charles and Camilla at Clarence House. Part of the tradition will see them eat a tier of William and Catherine's wedding cake to celebrate.
