The official statement released by Kensington Palace says that the 37-year-old is due to give birth in spring 2019 and of course, now royal fans are trying to pin down an exact timeframe.
Meghan Markle and Prince Harry are expecting a baby in Spring 2019! The trip is the first worldwide tour for the Duke and Duchess since they were married, apart from a two-day visit to Ireland. With Meghan's darker features mixed with Harry's lighter ones, Joe predicts that a baby girl would have dark hair and brown eyes, while a boy would have lighter brown hair and blue eyes.
The baby will be a first cousin of Prince George, Princess Charlotte and Prince Louis. In all, they have 76 engagements scheduled over 16 days in Australia, Fiji, Tonga and New Zealand.
The Duke and Duchess of Sussex are expecting their first child.
Royal expert Roya Nikkhah told CBS News correspondent Jonathan Vigliotti, who is traveling with the press entourage on a trip by Harry and Meghan to Australia and the South Pacific, that the announcement is an historic moment. Meghan had ended her acting career and moved to Britain to be a full-time royal. In 1917, King George V (Prince Harry's great-great-grandfather) reduced the amount of titles within the royal family, although Queen Elizabeth II could make an exception and allow Prince Harry and Meghan Markle's children to receive HRH (His or Her Royal Highness) titles.
I tin that Prince Harry will have two daughters.
The Palace Twitter handle shared a message stating that the couple are "pleased" to announce they are turning parents soon.
Meghan, who Wednesday Harry just five months ago, has had her 12 week scan and is believed to be due in late April.
And Meghan's mom also said she's "very happy" about becoming a grandma. We can just have so much fun together, and yet, I'll still find so much solace in her support.
