There was a flurry of activity on social media today after Prince Harry and Meghan finally gave the world their first proper glimpse of baby Archie.
The Duke and Duchess of Sussex released two photos to mark Archie’s christening, which took place at Windsor Castle on Saturday.
And in the rush to share the photos across all official channels, it seems Buckingham Palace’s social media team made a mistake in the process.
The second photo shared was a traditional royal family portrait, featuring the new family-of-three, alongside Prince Charles, Camilla, Prince William, Kate and Meghan’s mum Doria. The photo also featured Lady Jane Fellowes and Lady Sarah McCorquodale - Princess Diana’s sisters.
However, when releasing the official photographs on social media, The Royal Family Twitter account got Diana's sisters mixed up, and there were plenty of people that noticed.
Sharing who was featured in the photo from left to right, Buckingham Palace initially said Lady Sarah was beside Doria, and Lady Jane next to the Duke of Cambridge.
When in fact it was the other way around.
Officials have since corrected the error on the original post, however it took them a few hours to do so.
A lovely tribute to Diana in christening photos
Despite the error made, fans loved the inclusion of Diana’s sisters in the official snap.
Meghan’s mother Doria Ragland also featured in the family portrait after flying in from Los Angeles to be there.
No doubt Diana was there in thought. The inclusion of her sisters Lady Jane Fellowes and Lady Sarah McCorquodale in the portrait was a subtle tribute to Harry and William’s late mother.
Not the first royal mistake
It’s not the first time palace officials have made a slight error when it came to a milestone occasion.
Back in May when Archie was born a royal commentator suggested palace aides may have been caught off guard by the arrival of the Duke and Duchess of Sussex’s baby.
An announcement that Meghan, 37, had gone into labour in the early hours of Monday morning (GMT), was followed by another one less than an hour later, revealing that she had safely delivered a son.
When Yahoo UK contacted Buckingham Palace after the announcement Meghan was in labour, it seemed they were unaware that the Duke and Duchess of Sussex’s son had already been born.
They also made an error in the official announcement on the website when they announced the Duke and Duchess of Cambridge had welcomed a baby boy - not in fact the Duke and Duchess of Sussex.
