The Duchess of Sussex is eagerly awaiting the birth of her first child, but eagle-eyed royal fans are convinced that, rather than putting her feet up, Meghan is busy on social media.
Royal watchers have gone into a frenzy after spotting captions on the new @SussexRoyal Instagram account that they believe have been written by Meghan.
Fans fans have been quick to spot Americanised spellings, as well as dollar signs and American English in the captions, and claim this points to a US native writing them.
Meghan, 37, and Prince Harry, 34, recently thanked fans for donating to their chosen charities in honour of Baby Sussex, and one post about Baby2Baby contains references to 'cribs' and 'diapers'.
Several posts use the US spelling 'organization', rather than 'organisation' and 'programs' rather than 'programmes'.
Before she was the Duchess of Sussex and began dating Prince Harry, Meghan amassed millions of followers on social media, and loved interacting with her fans.
The former Suits star often posted on pictures of her doing yoga, cuddling her dogs and enjoying a glass of wine on her Instagram account.
In January last year when she shut down her profile, she released a statement via Kensington Palace, saying she was 'grateful to everyone who has followed her social media accounts over the years'.
At the time, she'd posted over 2,000 times and had millions of followers.
Fans are sure there are several clues as to whether Meghan is controlling the new Sussex Royal account, which so far has a total of 12 posts in just two weeks.
The account, which follows the work the royal's do for charities, patronages and any work engagements, has regularly posted in support of 'organizations', the Americanised-English spelling of the English word 'organisations'.
And it's not the only word which points to an American author - in the latest post, which thanks supporters of some of the royal's favourite charities, the occasional American spelling crops up, including 're-energized' instead of 're-energised'.
Both spellings of these words can be used in Britain, but the more common way in British English is 'energised' and 'organisations' with an 'S'.
In several posts, including one endorsing Baby2Baby, a charity in Los Angeles, the account uses the American spelling 'programs' rather than 'programmes'.
In the same post praising the Los Angeles charity, the writer refers to The Duchess of Sussex's 'hometown', the American spelling of the British word 'home town'.
The most recent post is perhaps the most heavily Americanised, and refers to baby essentials such as 'diaper' and 'crib' as opposed to words that English people tend to use, like 'nappy' or 'cot'.
The person writing the caption also used a dollar sign instead of a pound sign, which could indicate a clear slip from the author.
And it's not just the spelling which gives it away - the post in question is just one to feature the Oxford comma.
Despite it's name, it is not considered standard in UK English, but is mandatory in American English.
On posts specific to events the Duke of Sussex has attended, at which Meghan isn't present, the captions tend to follow with more traditional British English spellings.
Two of the Instagram posts in question also featured the heart emoji, a symbol never seen on the KensingtonRoyal account.
The SussexRoyal account features slick, white borders that give it a stylised look, in contrast to Prince William and Kate Middleton's account.
Since the SussexRoyal account has been launched, commentators have suggested that the Duke and Duchess may use it to post the first pictures of Baby Sussex.
And it was also reported last year that Meghan had a 'secret' Instagram account in order to keep up with friends and family.
She was even hands on with the Kensington Royal account, which she and Harry used to share with the Cambridges.
She snapped a photograph of her husband that appeared on the Kensington Royal feed during the royal tour last year.
The royal couple's split their social media accounts earlier this year and now the @Kensingtonroyal account purely documents the work of Prince William and Kate Middleton's family.
