Meghan Markle is expecting her second baby with Prince Harry, a spokesperson for the couple has confirmed.

The Duke and Duchess of Sussex, who are currently residing in California, are preparing to welcome a brother or sister for their son Archie, who will be two in May, later this year.

A spokesperson for Meghan and Harry said: ‘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.’

The couple shared their announcement – aptly on Valentine’s Day – by posting a black and white image of Harry resting his hand on Meghan’s head as she lay in his lap underneath a tree.

‘The photograph of the Duke and Duchess was was taken by the couple’s longtime friend Misan Harriman. What wonderful news for the Sussexes!!’ their spokesperson added.

If born in the U.S., the baby will be entitled to U.S. citizenship as an automatic right.

The news comes just months after Meghan, 39, revealed that she had suffered a miscarriage in an article for the New York Times.

It also comes on the 37th anniversary of when Harry’s mother, Princess Diana, announced that she was pregnant with him on Valentine’s Day in 1984.

Harry and Meghan shocked the world last year when they stepped down as senior royals and announced they were moving to North America with baby Archie, who will turn two in May.

The couple have been hunkering down at a sprawling nine-bedroom mansion in Montecito that they purchased for $14.65 million last June.

Their baby announcement came just days after Harry’s cousin Princess Eugenie welcomed a baby boy on February 9.

Meghan and Harry were said to have sent their congratulations to Eugenie privately, while keeping their own growing family under wraps.

The sex of the couple’s second baby, as well as the due date, remain unclear.

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

A Buckingham Palace spokesman responded to the news by telling ‘Her Majesty, Duke of Edinburgh, Prince of Wales and the entire family are delighted and wish them well.’

It is understood the Royal Family had been told in advance of the announcement. But it was not clear how much notice they were given.

Meghan recycled a Carolina Herrera dress made during her first pregnancy for the birth announcement photo.

Misan Harriman, the Nigerian-born British photographer who took the image, wrote on Twitter: ‘Meg, I was there at your wedding to witness this love story begin, and my friend, I am honoured to capture it grow.

‘Congratulations to The Duke and Duchess of Sussex on this joyous news!’

It’s unclear where the photo was taken but Harriman indicated that he took it remotely via an iPad.
