The big day is almost here!
The "private and intimate family event" should last approximately 45 minutes and will take place at the Chapel Royal at St. James' Palace at 3 p.m.
And when it comes to making sure that memories from the christening last forever, don't worry, the royals have that covered too.
A palace rota and official photographer will be on hand to capture the family's every picture-worthy move.
In fact, official christening photographs will be taken in Clarence House following the service.
And we won't have to wait long to see the royal family all dressed in their christening garb.
According to the palace's press release, a selection of official photographs will be released the following day on Thursday, Oct. 24.
So who can we expect to see at the fancy affair?
Buckingham Palace representatives have informed us that while "a guest list will be released nearer the time" of the ceremony, it has been confirmed that Princess Anne and Sophie, Countess of Wessex, will not be there.
And when it comes to the christening, a royal source tells E! News, "William and Kate are going to do things differently, and actually, their families are respectful of that. This won't be a case of a big rift. Christenings are not state occasions. They're private affairs and can be as big or intimate as the parents desire."
It's bound to be a royal spectacle!
