Prince William was left "perplexed" by Prince Harry and Meghan Markle's decision not to name their son Archie's godparents when he was christened, an updated book has claimed.
Archie was born in May 2019 and was christened two months later in a service at Windsor Castle.
Among those who attended the ceremony were Prince William, the Duchess of Cambridge, Prince Charles, the Duchess of Cornwall, Harry aunts and Princess Diana's sisters, Lady Jane Fellowes, Lady Sarah McCorquodale and Meghan's mum Doria.
At the time of the christening, the names of Archie's godparents were not announced and kept private by Harry and Meghan.
And according to the updated version of his unauthorised biography, Meghan: A Hollywood Princess, Andrew Morton says this left Prince William "perplexed".
He writes: "The decision to keep the names of the godparents secret was another issue, one of many, that perplexed William. He, like others inside the family, felt that those chosen to guide and counsel a future royal prince, seventh in line to the throne, should be identified. Harry and Meghan thought otherwise.
"They explained that the godparents were genuine friends, not celebrities or public figures, and had joined with the royal couple in preferring privacy."

Months after the christening, Harry and Meghan decided to quit as senior royals and left the UK to live in California.
They have since welcomed a second child, a daughter called Lilibet, who was born in the U.S and has yet to be brought to the UK for a visit.
Reports have suggested that the couple were keen to have the three-month-old christened in Britain like her older brother Archie.
He was younger than what Lilibet is now when he was baptised and it has also been claimed that a trip to the UK would also allow the Queen to meet her 11th great-grandchild for the first time.
However, on a recent edition of True Royalty TV's The Royal Beat, the assembled royal experts were asked if they could see Harry and Meghan returning to the UK soon for a christening.
But Hello!'s royal editor Emily Nash said: "I think that is fairly unlikely."
Royal historian Dr Andrew Lownie agreed as did the Sunday Times royal editor Roya Nikkhah.
Meanwhile, another royal expert previously said it is likely the infant will be christened in the US.
Author Richard Fitzwilliams told the Express : "Harry and Meghan’s relations with the British press went badly downhill when Archie was christened in private and the names of the godparents were not released.
"The Sussexes were emphatic that they intended to do things their own way and so it has proved.
"It must be likely that she will be christened in California though there are rumours of a possible christening at Windsor."
Andrew's Morton's updated version of Meghan: A Hollywood Princess is on sale online and in bookshops across the country from October 14.
