Prince George was the star of the show as he arrived in his father’s arms outside the Chapel Royal at St James’s Palace on Wednesday afternoon.
The Duke and Duchess of Cambridge looked on with pride as they were welcomed by the Archbishop of Canterbury outside the Chapel minutes before the service was due to begin.
William and Kate were joined by senior members of the Royal Family including The Queen and the Duke of Edinburgh.
Grandfather Prince Charles, the Duchess of Cornwall and Prince Harry were all in high spirits as they arrived smiling and doting on the family’s latest addition, Prince George.
As the crowds cheered outside the Palace, inside the walls it was the first time since Prince George’s birth that The Queen and the future three heirs had all been pictured together.
The new parents chose the Chapel Royal at St James’s Palace as they wanted to keep the christening a “small intimate affair”.
It is also significant to the couple as it where William’s mother Diana laid in rest before her funeral in 1997 and also where Kate chose to be confirmed into the Church of England before the royal wedding in 2011.
Three-month-old George was dressed in the replica Honiton lace gown and appeared to give his second royal wave as Prince William held him before the service.
The Duchess looked stunning as she arrived in an Alexander McQueen cream dress and a Jane Taylor Millinery fascinator.
Moments before the Royals arrived, Kate’s family entered the Chapel including Michael and Carole Middleton, who were joined by the Duchess’s siblings James and Pippa.
Prince George’s seven godparents were all waiting inside the Chapel as the royals made their entrance.
Prince William’s cousin Zara Phillips is among the seven honoured individuals who include close family William van Cutsem and close friend of the Princess of Wales’s, Julia Samuel.
The 30-minute service at the Chapel Royal included two hymns, two lessons and two anthems as Prince George is welcomed into the church.
The Hymns chosen by the parents were Breathe on Me, Breathe of God and Be Thou My Vision.
Surrounded by their closest family and friends, Prince William and Kate also asked Prince Harry and Pippa Middleton to read the two lessons.
William’s brother Harry read ‘St John ch 15, verses 1-5′ while the Duchess’ younger sister read ‘St Luke ch 18, verses 15-7’.
The third-in-line, who will one day become King, was on his best behaviour as he arrived outside the Chapel for his special day.
“He went in smiling, came out smiling and, as far as we are aware, smiled throughout,” a royal insider told the Mail Online.
Although Prince William did admit: “It’s the first time he’s been quiet all day.”
The service finished earlier than expected, and as the 23 guests left, which also included their part-time nanny, Jessie Webb, the Duchess carried her son out of the Chapel.
After this, guests headed to Clarence House where they were treated to afternoon tea by Prince Charles and the Duchess of Cornwall.
Guests, including close family and the seven godparents with their spouses, dined on slices of George’s christening cake, which is one of the tiers from William and Kate’s wedding cake.
While at Clarence House, the official portraits were taken by Hollywood photographer Jason Bell.
Although the christening was a private affair, official portraits will be released on Thursday for the world to see.
Speaking ahead of the christening, Jason, who has shot actresses Kate Winslet and Nicole Kidman, revealed he was thrilled to be taking the historic images.
“I’m honoured that the Duke and Duchess of Cambridge have asked me to photograph the christening of their son Prince George,” the photographer said in a statement. “I’m privileged to be recording this moment in history.”
There has been a lot of anticipation surrounding the official photos as it will be the first time in over a hundred years that a monarch and three heirs to the throne have been pictured together.
The last occasion that this happened was in 1894 when Queen Victoria was photographed with her son Edward VII, grandson George V and great-grandson Edward VIII.
