According to Kensington Palace, who tweeted the exciting news on Oct. 15, Meghan is due to give birth in the UK's spring.
In a statement, Kensington Palace said: “Their Royal Highnesses The Duke and Duchess of Sussex are very pleased to announce that The Duchess of Sussex is expecting a baby in the Spring of 2019.
“Their Royal Highnesses have appreciated all of the support they have received from people around the world since their wedding in May and are delighted to be able to share this happy news with the public.”
Given that Prince Harry and Meghan married at Windsor castle on 19 May 2018, it appears that the couple began trying for a baby straight away.
The news of the couple's impending arrival came just three days after they attended Princess Eugenie's royal wedding - held at the same location they tied the knot earlier this year.
Rumours swirled that Meghan was pregnant after the ceremony - as she attended the wedding wearing a blue coat which remained buttoned up throughout the ceremony.
