Here's what we know so far...
The Duke and Duchess of Cambridge welcomed Prince Louis to the world on 23rd April, releasing photos and the full name of the newborn to the world in the days that followed.
Their choice? Louis Arthur Charles - now fifth in line to the throne.
Since he was shown to the world on the steps of St Mary's hospital's Lindo Wing, the newborn Prince has been laying low, with the Cambridges spending the past two months bonding as a family in their Kensington Palace home.
Just this week however the details of Prince Louis' Christening were announced, and it looks like there's a special connection to Princess Diana.
'The Duke and Duchess of Cambridge are pleased to announce that the christening of Prince Louis will take place on Monday 9th July at The Chapel Royal, St James’s Palace, London,' the Kensington Royal account released in a statement.
'Prince Louis will be christened by The Archbishop of Canterbury, the Most Reverend Justin Welby.'
Prince Louis, like his older brother George, will be christened at The Chapel Room, which some are seeing as a tribute to his late grandmother, Princess Diana, whose coffin was laid there before her funeral in 1977.
We're sure The Chapel Room is very important to the family and we're looking forward to seeing the photos from Louis' Christening.
