The Duke and Duchess of Sussex have revealed that they are having a baby girl this summer.

Harry and Meghan shared the news that their son Archie will have a little sister during their interview with Oprah Winfrey.

The couple said their daughter will complete their family, with Meghan declaring: “Two is it.”

At the start of the interview, 39-year-old Meghan said she knows the gender of the baby, telling Winfrey: “We do this time. I will wait for my husband to join us and we can share that with you.”

Harry joined his wife in the second half of the interview, and told the chat show host: “It’s a girl.”

He said his first thought was “amazing” when he discovered the gender, adding: “Just grateful. 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, we got the four of us and our two dogs.”

Asked if they were “done” with two children, Harry said “done”, and Meghan said: “Two is it.”

She also confirmed the baby is due in the “summertime”.

Announcing the pregnancy last month, Harry and Meghan put out a black and white photo of themselves, in which they are sat under a tree in Los Angeles, with Harry gazing at his wife and resting his hand on her head as she lies in his lap cradling her bump.

The news came after the duchess suffered a miscarriage last summer.

Meghan revealed her miscarriage in November last year in a deeply personal article for the New York Times, writing: “I knew, as I clutched my firstborn child, that I was losing my second.”

Baby Sussex will be the Queen and the Duke of Edinburgh’s 10th or 11th great-grandchild, depending on whether she arrives before or after Zara Tindall’s baby, which is also due in 2021.

In 2019, proud father Harry announced the arrival of their firstborn Archie to a press pool, and then later held his newborn son in his arms, with Meghan at his side, for his public debut at Windsor Castle.

The new baby, like Archie, will grow up thousands of miles away from the Queen, the Prince of Wales, and the Duke and Duchess of Cambridge, as well as his or her cousins Prince George, Princess Charlotte and Prince Louis.

She will still be eighth-in-line to the throne – and the most senior royal in the current line of succession to be born overseas.

But she will not be entitled, at this stage, to be an HRH nor a princess due to rules set out more than 100 years ago by George V – but this is the same as what would have happened pre-Megxit.

The baby is entitled to be a Lady, but Harry and Meghan will again opt to style their second-born a plain Miss, with the surname Mountbatten-Windsor.
