Meghan Markle reportedly had a strong opinion about how Prince William was being treated compared to Prince Harry when they first met in 2017.
According to Robert Jobson's book, "Catherine, The Princess of Wales," Markle believed her now-husband "deserved more materially."
"It is understood that when Meghan and Harry had gone round to have drinks at William and Catherine’s apartment, while they were still living at Nottingham Cottage opposite, Meghan had been ‘taken aback’ at the disparity between the brothers," Jobson wrote in his book released last week, according to the New York Post.

"I am not saying Meghan was jealous, but she was really surprised how lavishly Harry’s brother was living compared to where they were living," Jobson wrote.
According to the royal correspondent and author, this was "perhaps the beginning of all the tensions between the two couples."
Fox News Digital has reached out to Harry and Markle for comment.
