Princess Charlotte was baptised in Sandringham, Norfolk on Sunday afternoon.
The Duchess of Cambridge, Prince William, and their son Prince George were dressed in their Sunday best for the happy occasion.
The world also got a new glimpse at the baby princess as she arrived for her christening.
The christening took place at St. Mary Magdalene Church, where members of the royal family worship regularly.
St Mary Magdalene Church #Sandringham is one of exceptional historic interest. Find out more http://t.co/1UEst4VWnN
The Queen attends the church when she is in residence at her Sandringham estate, and the royal family attends Christmas day service at the church.
St. Mary Magdalene Church is situated near the Duke and Duchess' second home, Amner Hall, where they intend to raise their two children.
Prince George arrived wearing the same outfit that Prince William wore to meet his brother Prince Harry, the second time he's worn an outfit like his father's recently.

As usual, Prince George won over fans with cuteness.
Prince George forever and ever Amen.
The little prince gave adorable looks to the crowd.
Prince George 💖
And won hearts by waving.
The small private service was also attended by the Queen and the Duke of Edinburgh, Prince Charles and the Duchess of Cornwall, the Duchess of Cambridge's parents, Carole and Michael Middleton, and her siblings, Pippa and James.
The Queen looked bright and summery in pastel pink.
Princess Charlotte's five godparents, Sophie Carter, James Meade, Adam Middleton, Laura Fellowes, and Thomas van Straubenzee, and their partners were the only other guests in attendance. The godparents were named by the palace earlier on Sunday morning.
Thomas van Straubenzee is one of William's oldest school friends and gave a speech at the Duke and Duchess' wedding. Sophie Carter and James Mead are friends of the royal couple.
Princess Charlotte was baptised using the Lily Font, once owned by Queen Victoria and usually kept among the crown jewells.
Princess Charlotte will be baptised in the Lily Font, commissioned by Queen Victoria and Prince Albert in 1840.
The font was filled with water flown in especially from the Jordan River in the Holy Land.
When it was announced where the water had come from, many people on Twitter felt it was an unnecessary extravagance.
The sky just turned black. Hope that wasn't my fault for casting doubt on the idea that River Jordan water has particular magic qualities.
And said it was wasteful.
Water from the River Jordan! What's wrong with the tap? https://t.co/JpXPxFhxgR
Others simply joked about it.
Pretty sure I've got a few cases of bottled River Jordan water in my shed.
Because, Twitter.
We brought the Holly water all the way from the river Jordan for today. It cost a bundl, but what the hell. Your paying for it after all!
The baby princess wore a replica of the Victorian lace gown used at all royal christenings, re-made by the queen's dressmaker, Angela Kelly.
The original Victorian lace and satin gown, worn at Royal christenings since 1841, has now been preserved.
Members of the public were invited to watch the royal family arrive at the event in an area named the "paddock".
Well-wishers began arriving early on Sunday morning to secure a good spot.
They battled off rain to get a glimpse of the royal family.
Rain or shine, I'll be going to #Sandringham today. Now patiently waiting for the bus at King's Lynn. If only I had a limo. 😂🇬🇧💙👑
