Prince Harry and Prince Andrew are portrayed in historian Andrew Lownie's new book as being quite adversarial toward each other. Their main beef, at least according to the book, is over Harry's wife Meghan Markle.

The Duke of Sussex, 40, was said to have left the disgraced Duke of York with a "bloody nose" following a "heated argument."

After Prince Harry and Meghan Markle's aides met with King Charles' team member, speculation arose on if the couple have plans to move back to the U.K.
