Meghan Markle and Prince Harry have received backlash from Tom Bower over their recent remarks.
The Duke and Duchess of Sussex have been called out for their unprofessional behaviour just a day after Variety revealed Netflix insider opinion on the couple.
Mr Bower told the Express: "The Variety article endorses what I described in my book, Betrayal. The Sussexes are reaching the end of the road in Hollywood.
"Their behaviour, lack of original talent and suffocating self-importance has made it even more important for them to return to Britain in July, meet the King and be revalidated as royals."
Mr Bower added: "That option, I believe, will be denied to them. They face an increasingly tough future. That's the price of betraying the Royal Family since Megxit."
This comes as a rep for Harry and Meghan noted: "This is someone who has publicly stated, 'the monarchy in fact depends on actually obliterating the Sussexes from our state of life,' language that speaks for itself.
"He has made a career out of constructing ever more elaborate theories about people he does not know and has never met. Those interested in facts will look elsewhere; those seeking deranged conspiracy and melodrama know exactly where to find him."
