The star of The Wire and The Affair could be set to take over the role from Josh O'Connor.
The part was originally played by child star Billy Jenkins in the first two seasons before current star Josh O'Connor began playing him from season three.
And if West was to be confirmed as the new star, he'd be playing the royal at a crucial time in his life, during his affair with Camilla Parker Bowles, who would, of course, later become his second wife.
When approached by RadioTimes.com, Netflix declined to comment.
West has had a stellar career in film and TV – in addition to his aforementioned roles he has also starred in Chicago, 300 and as Jean Valjean in the recent BBC adaptation of Les Miserables.
