Yesterday, we reported that Prince Harry and Meghan Markle had agreed to do a tell-all interview with Oprah Winfrey. Now, Winfrey’s best friend Gayle King is saying that “nothing is off limits” in this interview.

“I know she’s been working on the questions all weekend long,” King said of Winfrey. “I’m told nothing is off limits, nothing is off limits. She can ask anything she wants.”

Meghan and Harry will be sitting down with Winfrey, who happens to be their neighbor, for “Oprah With Meghan and Harry: A CBS Primetime Special,” which is set to air on March 7.

“Oprah Winfrey as she sits down with Prince Harry and Meghan, The Duke and Duchess of Sussex, for an intimate conversation for an exclusive primetime special,” states a press release for the special. “Winfrey will speak with Meghan, The Duchess of Sussex, in a wide-ranging interview, covering everything from stepping into life as a Royal, marriage, motherhood, philanthropic work to how she is handling life under intense public pressure.’

“Later, the two are joined by Prince Harry as they speak about their move to the United States and their future hopes and dreams for their expanding family,” the press release added.

Though it is unknown if they gave Harry’s grandmother Queen Elizabeth a heads up before making this announcement, a source is saying that they are “under no obligation” to let the royal family know about their plans.

“The Duke and Duchess are no longer working members of the royal family and therefore any decisions they take with regard to media commitments are matters for them,” the source told Entertainment Tonight. “As non-working members of the royal family, they are under no obligation to inform the royal household of such plans.”

This comes after Meghan and Harry announced that they are expecting their second child.

“We can confirm that Archie is going to be a big brother. The Duke and Duchess of Sussex are overjoyed to be expecting their second child,” their spokesperson said. They are already parents to Archie Harrison, who turns two this coming May.

Meghan and Harry shocked the world last year when they announced that they were stepping down as senior royals. They then moved across the world to the ritzy area of Montecito, California, where they have signed lucrative deals to create content for Netflix and Spotify.
