Meghan Markle and Prince Harry have announced the birth of their daughter

Meghan Markle and Prince Harry have announced the birth of a baby girl named Lilibet 'Lili' Diana Mountbatten-Windsor.

• The royal couple, who are now based in California, already have a son, Archie, who has just turned two.
• In a nod to Harry's late mother, they have given their daughter the middle name of Diana.
• In other royal news, is this the reason Kate and William could be spending more time in Scotland?

A message on the couple's Archewell website said, "On June 4, we were blessed with the arrival of our daughter, Lili.

"She is more than we could have ever imagined, and we remain grateful for the love and prayers we've felt from across the globe.

"Thank you for your continued kindness and support during this very special time for our family."

They announced their happy news in February, that they were pregnant with a little girl, with a sweet photograph taken by Misan Harriman.

However, the couple never revealed how far along Meghan was with her pregnancy, but some predicted that she could give birth next Thursday—on what would have been Prince Philip's 100th birthday.

But now all the speculation can stop—as the royal couple welcomed a new addition to their family on Friday—and we love the name they've chosen.

Lilibet Diana Mountbatten-Windsor will be a little sister to two-year-old Archie, while the couple has also indicated that they will be calling her 'Lili' for short. 

Their daughter's first name, who was born at Santa Barbara Cottage Hospital, is said to be after the Queen's nickname—known as Lilibet by her family.

Royal fans will also love how they have given a massive nod to Prince Harry and William's late mother Princess Diana with Lili's middle name.

Harry has spoken openly about his mother and the effect her death had on him at such a young age. In the first episode of the five-part Apple TV+ documentary, which was co-created with Oprah Winfrey, Harry explained how his unresolved grief led to anxiety and panic attacks in adulthood. 

The duke was just 12 when his mother, Princess Diana of Wales, was killed tragically in a car crash. 

"I was willing to drink, I was willing to take drugs, I was willing to try and do the things that made me feel less like I was feeling," he told Oprah. 

While pregnant Meghan and Harry were also interviewed by Oprah about why they left the royal family and the Duchess's mental health struggles.

Two years after they tied the knot, with Meghan Markle's wedding dress capturing the nation's imaginations, the couple moved to California with son Archie. They have since picked up various deals, including one with Netflix. Meghan's children's picture book is due to be released on Tuesday. 

2021 has already shaped up to be quite the year for royal babies. Princess Eugenie welcomed her first child with her husband Jack Brooksbank in February, a boy named August Philip Hawke Brooksbank.

Meanwhile, Zara and Mike Tindall welcomed their third child, also a baby boy, named Lucas Philip Tindall, at the end of March.
