Meghan Markle sparks theory as eagle-eyed fans spot bizarre detail in new Instagram post

Apparently, something's not quite right with Meghan Markle's 2025 Instagram return.

Following the Duchess' shock return to social media yesterday (1 January), some of her most eagle-eyed followers believe they've spotted a series of cryptic errors in her very first upload, and are trying to make sense of what it means.

Take a look:

Prior to her New Year's Day upload, neither Meghan nor her husband Prince Harry had used social media for a staggering four years.

The couple - who wed in 2018 - had an official royal account @sussex.royal set up the following year.

But in 2021, they reportedly shut it down after being subjected to an onslaught of criticism from online trolls after they stepped away from their royal duties moved from the UK to the US.

But the mother-of-two has now made her comeback, kicking off 2025 with a video of herself running barefoot on the beach - presumably close to their house in Montecito, California - before she writes the numbers '2025' in the sand.

However, some of the 43-year-old's new online followers have been looking closely at Meghan's video.

And as such, they've noticed that something doesn't quite add up in the formatting of the clip.

The sweet tribute to the year ahead ends with her writing her note in the sand, with the remainder of the clip seemingly showing the royal looking carefully for the perfect place to write it.

It is after she finishes writing her message in cursive that Meghan looks back at the camera and smiles, before running out of view.

Some Instagram users have noticed, however, that the four-digits were already seen inscribed into it in the background of the beginning of the video, believing the video as a whole may actually have been filmed more than once.

This isn't the only intriguing aspect of the video to have left viewers stumped.

The meaning behind the Meghan's message in the sand has divided opinion - especially among royal experts - with some adamant she's simply ringing in the New Year, and others believing she's sending out a 'hidden message'.

Royal commentator Ingrid Seward told The Sun today that she believes the Duchess wants to start 2025 off on a 'strong note' by 'separating' herself from her husband and their two children.

"I think it's a positive message," she explained. "'Hi, I'm here. I'm back. I'm doing my thing, and Harry will be doing his thing, and I should be doing mine'.

"They've been sort of dogged a bit last year by lots of rumours about the state of their marriage, and whether Harry was happy and why we haven't seen more of Meghan, and I think she realises that she wants to start 2025 on a very positive and sort of strong note.

"You know, 'look at me, I'm here. Watch out for me and what I'm doing'."

That wasn't the end of Seward's assessment, however - and she also made a interesting prediction about Meghan's future plans in the online sphere.

Believing she plans to forge a 'new beginning' for herself this year, she added: "This is the first video she's posted on her new video site, which she's called just Meghan, which I think is quite nice.

"[Meghan's] supposedly got her cooking program, her lifestyle program coming up. I think we'll probably be getting many, many more."
