Prince William and Prince Harry have grown apart since the latter left the royal family, but even before the big move, the Duke of Cambridge found himself frustrated with his younger brother.
According to The Mirror, an updated version of Andrew Morton's unauthorized biography Meghan: A Hollywood Princess details how William didn't like the way that Harry went about 2-year-old son Archie's christening.
"The decision to keep the names of the godparents secret was another issue, one of many, that perplexed William," the author writes. "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," continued the royal expert. "They explained that the godparents were genuine friends, not celebrities or public figures, and had joined with the royal couple in preferring privacy."
The Sussexes have still yet to share the names of Archie's godparents, and they also haven't identified the godparents of their daughter Lilibet, who was born in June.
At the moment, details of Lilibet's christening haven't been made public, but many speculate that Harry wants the milestone to occur in England.
"Harry told several people that they want to have Lili christened at Windsor, just like her brother," a royal source told the Daily Mail. "They are happy to wait until circumstances allow."
However, others believe the tension is still too high, so they may just opt to do the ceremony in California without the royal family present.
"It must be likely that she will be christened in California though there were rumors of a possible christening at Windsor," royal commentator Richard Fitzwilliams told the Daily Express. "It seems certain that her christening will be in Meghan’s home state and with the secrecy but without the controversy that surrounded Archie’s christening."
"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," he added. "The Sussexes were emphatic that they intended to do things their own way and so it has proved."
