Netflix drops the final episodes of “Harry & Megan” today, but it doesn’t matter what’s on them:  The relationship between Harry and his brother Prince William is already toast.

A so-called “source” close to the Royals says, “The relationship between the brothers is over . . . William will never forgive Harry for selling out his and Kate’s secrets.

“Harry knows, more than anyone, how much their privacy means to William and Kate . . . It’s just sickening to [William] that Harry, who knows exactly how distressing it will be to him, is now selling them out to the media.”

Pouring even more fuel on the fire, “Harry & Megan” is already Netflix’s biggest documentary debut of all time.  People watched 81.55 million hours of it within its first four days of release.
