With Prince George's christening just hours away, finishing touches for the once-in-a-lifetime event are being put into place.
But what can we expect from the special affair?
E! News takes a look at the British traditions that the royal family will most likely implement for the future heir's big day.
First things first, the event of the year will take place in the Chapel Royal at St. James' Palace in London and will last roughly 45 minutes.
The duration of the private ceremony is typical for royal baptism as is the location.
In fact, St. James' Palace has held at least 18 royal ceremonies over the years (making it the most popular location for such an occasion) and is where Prince William's mother Princess Diana's casket was placed just before her funeral in September 1997.
We also know that the little prince will be donning an all-white Spitalfields silk-satin gown that has been previously worn by 60 other royal babies
The designer, Janet Sutherland, first created the garment with cotton lace overlay in 1841 for Queen Victoria's eldest daughter.
At the time, she was gifted the honorable title of Embroiderer to the Queen. Fancy stuff!
And as the spiritual head of the Church of England, it's tradition that the Archbishop of Canterbury leads the private ceremony.
The current archbishop, Justin Welby, will preside over the Prince of Cambridge's "absolutely private" affair.
Another tradition that takes place for such a special day involves the Lily Font.
The royal relic, which will be used to carry consecrated water from the River Jordan, is expected to be taken from the Tower of London where it forms part of the Crown Jewels (as do various christening cups and bowls).
The family's use of this water dates back to King Richard I in 1157.
There's one last custom that the royal family partakes in for a christening, and it involves cake.
That's right, some very special guests of the baptism ceremony will enjoy the top layer of Prince William and Kate Middleton's wedding cake, dating back to 2011.
At the Duke of Cambridge's christening in 1982, pieces of Prince Charles and Princess Diana's cake were distributed to an elite group of Welsh crowds.
Considering this marks the first christening since Princess Louise's in 2004, this event is surely going to be unforgettable!
