People think they've already worked out Meghan Markle's due date

We spy a baby bump!

News that Meghan Markle is pregnant may have only just broken, but the public reckon they've already worked out her due date.

Kensington Palace shared news on Twitter that the Duke and Duchess of Sussex will welcome their first child in spring next year.

Royal fans have noted that it's usually the case that news of a pregnancy isn't shared before the 12-week mark, or the end of the first trimester.

While there's been no official confirmation of exactly how far along Meghan is, people are assuming the timing of the news means she is currently around 12 weeks pregnant – which would mean the due date is April.

Of course, the exact due date is unlikely to be made known outside of the royal family; as with Kate Middleton's pregnancies we probably won't know anything until the couple checks into the Lindo Wing at St Mary's Hospital – or even until after the baby's arrival. (Speaking of St Mary's, Pippa Middleton and James Matthews have just been spotted at the Lindo Wing themselves).

Excitingly, Meghan is already sporting a small baby bump which could be seen on the first day of her tour of Australia. The Duchess wore a white dress by designer Karen Gee (which, no surprise, caused the website to crash), as well as earrings that once belonged to Princess Diana, according to Mail Online.

We're sure you'll agree that pregnancy suits the duchess. Needless to say we're already excited for spring 2019...
