The venue and date for Prince George's christening have been confirmed - 23 October at the Chapel Royal at St James' Palace.
The Chapel Royal is full of sentiment for Prince William as it is where his mother, Diana, Princess of Wales, lay in front of the altar for a week after she died.
The Duke and his brother Harry visited their mother there to say their goodbyes before her funeral at Westminster Abbey.
The Archbishop of Canterbury will carry out the service, and said it is a "privilege and an honour' to carry out the baptism.
According to the Daily Telegraph, the Duke's biographer suggested the choice, which was made over other venues, including St George's Chapel where Prince Harry was christened, was a way of including his mother in the ceremony.
Penny Junor told the paper: "There is a recurrent theme of making sure Diana is very much in his thoughts and in his heart, and I think this is a little way of including her."
And the bets are on as to who will be the young prince's Godparents.
Kate's sister, Pippa Middleton, and brother, James Middleton, and William's brother, Prince Harry, are obvious possibles, but there are friends of the Royal couple who are also being thrown into the mix.
William's friend James Meade, who recently married Lady Laura, as well as family friends Hugh Van Cutsem and Guy Pelly have odds on them at Ladbroke's, reports the Daily Mail.
William's stepsister, Laura Lopes, is also being seen as a possible Godmother.
Then there are other members of the Royal Family to be considered, like William's cousins Peter Phillips and Zara Phillips. Who do you think will make the cut?
Meanwhile, the Express reports that the Duke and Duchess will move into their newly-renovated Kensington Palace home as soon as this week.
They have spent the last two weeks enjoying a holiday at Balmoral, the Queen's Scottish estate, but will move into their four-storey 20-room apartment "within days".
