George also revealed he will wait to watch the interview in full when it airs on ITV tonight.
He added: “I will watch it tonight for sure. I’m not a royalist.
“I’m not anti royal or anti Meghan. The comparisons to Princess Diana are pretty lame.
“She walked in blind. Meghan was a Hollywood actress.”
The landmark interview will be shown in full on ITV tonight, with the broadcaster scrapping their usual schedule to air it.
Oprah With Meghan and Harry is on ITV at 9pm on Monday March 8. You can watch the full interview afterwards on the ITV hub.
