Meghan Markle and Prince Harry will not tell fans who they have picked to be their son Archie's godparents.
The Duke and Duchess of Sussex have released details about the christening, which will take place on Saturday, but have said they are keeping the names secret.
They've said this is "in keeping with their wishes".
They have also announced that they will release official photos from the day at a later point.
The Archbishop of Canterbury will do the christening at the Private Chapel in Windsor Castle, and the couple have asked photographer Chris Allerton to take pictures on their special day.
The news will disappoint many royal fans who were looking forward to seeing snaps of the Sussexes arrive at the service.
A statement, released by Buckingham Palace today, reads: "Archie Harrison Mountbatten-Windsor will be christened in a small private ceremony by the Archbishop of Canterbury in the Private Chapel at Windsor Castle on Saturday 6 July.
"The Duke and Duchess of Sussex look forward to sharing some images taken on the day by photographer Chris Allerton.
"The godparents, in keeping with their wishes, will remain private."
About 25 people are set to attend the celebrations, including members of the family, close friends and the Godparents.
The family event is expected to be attended by the Prince of Wales, the Duchess of Cornwall and the Duke and Duchess of Cambridge.
One key member - the Queen - will not be there because of prior commitments, the Sunday Times reports.
Royal christenings are never normally broadcast on TV. However parents normally invite members of the press to take pictures outside.
We normally get lovely shots of the family arriving, and Louis's christening was the first time we saw the Cambridges together as a family of five.
