• Meghan Markle and Prince Harry's sit-down interview with Oprah Winfrey will air on March 7 on CBS
  • The Duchess of Sussex will talk about "marriage, motherhood and how she is handling life under intense public pressure"
  • Prince Harry will join them as they talk about their move to the U.S. and future plans

Meghan Markle and Prince Harry are breaking their silence in an upcoming tell-all interview with Oprah Winfrey following their announcement that they are expecting their second child.

The Duke and Duchess of Sussex will sit down for an "intimate conversation" with Winfrey for "Oprah with Meghan and Harry: A CBS Primetime Special," which airs March 7 at 8 p.m. EST/PST on CBS, the network announced Monday. This will be Markle's first major TV network interview since she and Prince Harry stepped back as senior royals last year.

In a statement, CBS said Markle's chat with Winfrey will be "a wide-ranging interview covering everything from stepping into life as a royal, marriage, motherhood (and) philanthropic work, to how she is handling life under intense public pressure," The Oprah Magazine reported.

Prince Harry will join them as they talk about "their move to the United States and their future hopes and dreams for their expanding family," according to the press release.

News of their interview comes shortly after Markle and Prince Harry revealed Sunday that their son Archie will soon be a big brother.

Some royal watchers and commenters believe that the couple may have been paying tribute to his mother, Princess Diana, with the timing of their announcement. News that the late Princess of Wales was expecting her second child with Prince Charles made headlines on Valentine's Day in 1984.

Prince Harry and Markle agreeing to be interviewed by Winfrey may not come as a surprise to some. The couple has a longstanding relationship with the TV host. In fact, in 2019, Winfrey announced that she was teaming up with Apple and Prince Harry for a multi-part series that will focus on mental health and mental wellness, a project that is still in production.

Winfrey was also among the celebrity guests who received invitations to the Duke and Duchess of Sussex's royal wedding in May 2018, along with George Clooney and his wife, Amal. It was also believed that Winfrey introduced Prince Harry and Markle to her circle of friends, including Tyler Perry.

Prince Harry and Markle stayed at Perry's mansion when they first moved to California last year and before they purchased their $14 million mansion in Montecito.

Meanwhile, the announcement of Markle and Prince Harry's interview with Winfrey received mixed responses from Twitter users. Some accused Markle of cashing in on her pregnancy and marriage.

"Wonder how much they’ll get paid for this?!?!? Meghans agenda the entire time was to cash in on this marriage both in cash and additional fame!" one commented.

"Oh no! Please don't do this. I was so thrilled when Meghan joined the royal family. I am so disappointed now with both of them. A missed opportunity," another wrote.

Others, however, came to Markle's defense and expressed their excitement over the upcoming special.

"She had cash and fame before she married," one wrote.

"People who are interviewed by Oprah are not paid," a second user added.

"Hoping one of you many wonderful people can record this and upload it youtube or somewhere. Many of us outside of America will not have access to this," a third user wrote.

"Yaaay!!!! That's going to be a Fantastic Interview Oprah's REALLY Good interviewing her Guest Love to see that interview Meagan and Harry and Previous People," another added.
