Netflix is said to have put out a casting call already for the character, approaching tonnes of drama clubs and schools in the hopes of finding somebody to play the future heir.
An insider told the Times that searching for the Duke of Cambridge had only just begun, and producers were also set to hunt for somebody to play Prince Harry in the coming months.
Kids aged between nine and thirteen will be considered by casting director, Nina Gold, reports state.
It comes after the baby prince was briefly played by Lucas Barber-Grant in the fourth series.
While the casting may be exciting for fans, who are gearing up for another season to binge, the bad news is its only the very first step in a very long process.
It's not expected that The Crown will start filming until the summer, and it's not expected to air until 2022, so there's a long old wait before the royal drama is back on screens.
The next series of the Netflix show is set to cover the early 1990s, covering topics including the Windsor Castle fire and the end of three of the Queen's children's marriages.
There is still speculation as to whether the death of Diana, Princess of Wales will be covered (this took place in Paris in August 1997), as Netflix have not yet confirmed the exact series synopsis.
What we do know is that Jonathan Pryce, 73, will be starring as Prince Philip in season five, while Imelda Staunton replaces Olivia Colman as The Queen.
Lesley Manville is set to step up into the role of Princess Margaret, while Emma Corrin is being replaced by Elizabeth Debicki for the final two seasons.
Tyla has contacted Netflix for more deets on the casting.
More announcements and details on the plot will follow as we know them...
