The second child of Harry and Meghan, the Duke and Duchess of Sussex, will be a girl, the couple announced Sunday in a tell-all interview with Oprah Winfrey.

"It's a girl," Harry told Winfrey, after Meghan waited for him to join the interview so they could share the news together.

"Amazing. Just grateful," Harry said of his own reaction. "To have any child, any one or any two, would have been amazing, but to have a boy and then a girl, I mean, what more can you ask for?"

"Now we've got our family," he said. "We've got, you know, the four of us and our two dogs."

The couple said their baby girl is due this summer, and they’re not planning to have more children after that.

Harry and Meghan, the parents of nearly 2-year-old Archie, revealed they are expecting their second child on Valentine's Day, less than three months after Meghan opened up in a New York Times op-ed about a pregnancy loss the couple suffered last summer.

In a statement confirming Meghan's pregnancy at the time, a spokesperson for Harry and Meghan described the couple as "overjoyed to be expecting their second child." The Sussexes announced the pregnancy by sharing a photo of themselves at home in California.

The photo was taken remotely from London by photographer Misan Harriman, a friend of the couple's who attended their 2018 wedding.

"In the age of COVID, it’s impossible obviously for me to be there to shoot it, so technology came to rescue," Misan Harriman told "Good Morning America last month." "I was able to remotely take over the iPad and they could hear my voice and it was conversational and the rest really is history."

Harriman photographed Harry and Meghan in front of a deep-rooted tree, with Meghan's head resting on Harry's lap.

"You don’t even see the image, you feel it," Harriman said. "They are lost in each other. And the tree in the background and just life growing around them is incredibly powerful and symbolic."

Harriman told "GMA" he hopes people see in the photo of Harry and Meghan the symbolism of "fortitude, hope and love."

"Particularly for the many women going through this, this should give them strength to know there’s light in that dark place," he said. "It really means a lot."

Harriman, the first Black man to shoot the cover for British Vogue, said to see to see the couple now expecting their second child is a "testament to the power" of their relationship.

"Honestly I think the universe would have conspired for them to be together no matter what. It is the real deal. They are waltzing through life together, as it should be," said Harriman. "To have a new arrival coming is a testament to the power of the relationship that they have."

Harry and Meghan's pregnancy announcement mirrors the late Princess Diana's announcement 37 years ago when it was confirmed she was pregnant with Harry. According to ABC News royal contributor Omid Scobie, news of Diana's pregnancy was announced on February 13, 1984, and hit the newspapers one day later, on Valentine's Day.

Harry and Meghan's second child will be the fifth grandchild for Prince Charles and the 10th great-grandchild for Queen Elizabeth. The baby will also be the first senior royal baby born in the United States and the first great-grandchild of the queen to be born outside of the United Kingdom.

Meghan gave birth to Archie in a London-area hospital on May 6, 2019.
