According to Sunrise's royal expert and biographer, Rob Jobson, once Queen Elizabeth abdicates the throne, Prince Harry and Meghan Markle's son will be crowned Prince Archie.
"Everyone is going on about the fact that he is just going to be 'Master Archie' - I think that is just for now," he explained.
"The Queen is 93-years-old, and they didn’t want to make a big fuss for the rules to be changed.
"There is a thing called the George V Convention, which was to stop so many 'prince' names.
"When Prince Charles becomes king, I have been told they are very happy for him to become ‘Prince Archie’, that is with their blessing. It’s not a speculative thing, that’s exactly what they will do.
Another royal commentator, James Brookes explained, "Of course, when Charles becomes King - Archie becomes a male-line grandchild of the monarch and so is eligible to be titled as Prince and use HRH."
