The two-hour special will air on 10 and 10 play on Monday, 8 March at 7.30 and will also be available to watch on demand on 10 play

Ahead of it airing, the interview has already created a worldwide stir, with Oprah sitting down and having a one-on-one conversation with Meghan before Harry joins the conversation.

Said to cover absolutely everything from their marriage to their unprecedented move to Los Angeles, Meghan will also speak about her life after becoming part of the Royal Family and the intense scrutiny she faced.

On Valentine’s Day, the Duke and Duchess announced they were expecting their second child, and the pair are said to also discuss their hopes for their expanding family with Oprah.

In a preview released by CBS, Oprah made it clear that “there is no subject off-limits”, and in another clip, Meghan opened up about how she believed the Palace would react to her speaking openly about her life.

“I don’t know how they could expect that, after all this time, we would still just be silent,” Meghan said, adding, “if that comes with risk of losing things… I mean, there’s a lot that’s been lost already.”

In a shocking admission, Harry told Oprah his fears that history would repeat itself, referring to the tragic death of his mother, Diana.

“I’m just really relieved and happy to be sitting her talking to you with my wife by my side,” Harry said in the clip, “Because I can’t imagine what it must have been like for her [Diana], going through this process by herself all those years ago.

“It’s been unbelievably tough for the two of us, but at least we had each other.”

The special is set to air on the CBS Network from 8 to 10pm ET/PT on Sunday, and for Aussies it will be available to watch Monday, 8 March at 7.30 on Network 10 and live streamed on 10 play.
