Prince William and Kate Middleton's baby boy will be participating in a royal tradition today—his christening!
The ceremony, which is scheduled to take place at 3 p.m., is expected to last approximately 45 minutes, and the couple's firstborn will be baptized by the Archbishop of Canterbury, the Most Reverend Justin Welby.
"William and Kate are going to do things differently, and actually, their families are respectful of that," a royal source previously told E! News. "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."
And just yesterday, Kensington Palace announced that the Duke and Duchess of Cambridge have chosen Jason Bell as the official photographer for the momentous occasion.
"I'm honored that the Duke and Duchess of Cambridge have asked me to photograph the christening of their son Prince George," Bell said in a statement. "I'm privileged to be recording this moment in history." A moment in history, indeed!
Luckily, we won't have to wait long to see the famous photographs of the royal family in their christening wear, as a selection of official photographs will be released tomorrow, on Thursday, Oct. 24, according to Kensington Palace.
But before we take a look at the future king in his all-white Spitalfields silk-satin gown that has been previously worn by 60 other royal babies, let's take a look back at some other royals' christening photos!
