Prince Harry and Meghan Markle surprised royal watchers as they announced another milestone in their life.

In a statement obtained by Page Six, a representative shared that the former "Suits" star is expecting her second child.

"We can confirm that Archie is going to be a big brother," a spokesperson for the couple told the outlet. "The Duke and Duchess of Sussex are overjoyed to be expecting their second child."

Interestingly, the surprising news was revealed exactly on Valentine's day, and just days after Prince Harry's cousin, Princess Eugenie, gave birth to her first child. Last week, Buckingham Palace announced that the royal family had given birth to a healthy baby boy, who she shares with her husband, Jack Brooksbank.

Although the representative did not disclose further details such as the baby's gender or her expected due date, rumors about Meghan Markle's pregnancy sparked in December after she was photographed wearing an oversized black sweater and a heavy parka in Beverly Hills.

This was amid her privacy case trial against the British tabloid, Mail on Sunday.

A dreamy portrait, shot by the renowned photographer and the couple's longtime friend, Misan Harriman, features a black and white photo of the couple in what appears to be a backyard.

"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!" the photographer wrote.

Prince Harry was spotted sporting a flowy long-sleeved top, paired with dark trousers while the 39-year-old duchess was seen cradling her baby bump.

Meghan Markle's Pregnancy Dress by Carolina Herrera

Interestingly, Harper's Bazaar revealed that the former actress was wearing a custom made dress by famous designer Carolina Herrera.

Moreover, the bespoke dress was designed while pregnant with her first child, Archie Harrison Mountbatten-Windsor. Meghan Markle's son will be turning two this May 6.

Over the years, the former royal was often spotted donning a piece from the Venezuelan fashion designer.

It is safe to say that the duchess was a fan of Herrera's works, known for her exceptional personal style.

The renowned designer's famous clients also include high profile clients such as First Ladies, including Jacqueline Onassis, Michelle Obama, Laura Bush, and Melania Trump.

In 2018, she wore a baby pink off-shoulder dress during her first trooping of colors. This was then followed by her custom made printed blue midi dress during their visit with the King of Morocco in 2019. At the time, Meghan Markle was pregnant with baby Archie.
