Guests are arriving at St Mary Magdalene Church, Sandringham for the christening of Princess Charlotte.
Thousands of onlookers have gathered to get a glimpse of the proud parents, the Duke and Duchess of Cornwall and the baby princess.
One woman from Florida even gave away her British Grand Prix ticket to be here.
The Queen and the Duke of Edinburgh’s arrival was closely followed by William and Kate with George walking beside them and Charlotte in her pram.
The service itself will be conducted by the Archbishop of Canterbury, supported by the Rector of Sandringham group of parishes, Rev Canon Jonathan Riviere.
