“I just want to make it clear to everyone that no subject is off-limits,” Oprah says in the first look at her upcoming interview with the Duke and Duchess of Sussex, Prince Harry and Meghan Markle, set to air on CBS in a week’s time. 

The highly anticipated conversation will be the couple’s first joint interview since announcing their engagement in 2017 and CBS’ Gayle King, a reporter and longtime best friend to Oprah, has said Oprah considers this “the best interview she’s ever done.” 

In the clip, the trio sit outside in the sprawling Montecito, California backyard of Prince Harry and Markle. The couple is clearly emotional in the clip—tears pool in Markle’s eyes as Oprah says to her, “it sounds like there was a breaking point,” seemingly referencing the family’s decision to step away from the royal family and relocate to Los Angeles. 

Though we don’t hear Markle speak in the short clip, Prince Harry references his mother’s death, saying, “My biggest concern was history repeating itself.” 

“For me, I’m just really happy to be sitting here talking to you with my wife by my side,” he tells Oprah. “Because I can’t begin to imagine what it must have been like for her [Princess Diana] going through this process by herself all those years ago. It has been unbelievably tough for the two of us but at least we had each other.”

CBS has said that the interview, which was originally intended to be ninety minutes, has been expanded to two hours to include the entire conversation. The interview will begin with a conversation between Markle and Winfrey, which will cover “everything from stepping into life as a Royal, marriage, motherhood, philanthropic work to how she is handling life under intense public pressure.” Prince Harry will then join the pair to speak about the couple’s “move to the United States and their future hopes and dreams for their expanding family.”

The Duke and Duchess have been close with Winfrey since they were introduced back in 2017. The talk show host attended the royal wedding in 2018 at Windsor Castle, and is now the couple’s neighbour—Winfrey also resides in Montecito, close to where the Markle and the Prince live.
