The christening was held in an intimate ceremony in California last week, where the Archbishop of Los Angeles, the Rev John Taylor, officiated the ceremony.
According to a spokesperson, the appropriate conversations had taken place before the announcement.
Roya Nikkha, a royal expert, shared that Charles had spoken to his son to inquire about his children's preferred titles. As per the 1917 letters patent issued by King George V, using the royal titles of Archie Harrison and Lilibet is perfectly acceptable.
However, despite this, the titles have not been updated on the royal website. Nikkha stated that Harry would want his children to have the freedom to choose their titles when they come of age.
She added that it's up to Charles whether he decides to remove their titles by issuing letters patent. The matter remains unresolved.
