Amidst all the pomp and ceremony, royal fans have spotted an eerie guest at King Charles' Coronation in Westminster Abbey.
Chares has officially been crowned as King as millions around the world watch in awe, but eagle-eyed viewers have also spotted a spooky presence in the London church.
Royal lovers rushed to Twitter to share snaps of a mysterious figure, dubbed the 'Grim Reaper'.
Social media Joe Green, who posts on account @realjoegreeeen, shared the discovery of the spooky character, otherwise known as the personified figure of death.
Joe shared a clip from the ceremony where a figure walked by the doors of Westminster Abbey donning the mythological character's iconic dark robes and an item giving a similar appearance to a scythe.
Since sharing the spooky clip, Joe's video has raked in over 225,000 views to date.
Alongside the video footage, he asked Twitter users: "Anyone else just notice the Grim Reaper at Westminster Abbey #Coronation?"
One person claimed they also spotted the figure as they wrote: "Thanks. Thought I was going mad."
A second said: "Yes! I thought it was a witch!"
"I saw him too!" A third Twitter user penned alongside four laughing emojis.
A confused fan couldn't believe their eyes and questioned: "Did someone just edit this in or was that actually someone walking past?"
Meanwhile, one person found joy in the situation: "This might just be my favourite moment of the #Coronation."
"That's amazing," a second person agreed.
On the other hand, a royal found the situation quite terrifying as they said: "Not a good sign is it."
King Charles III's Coronation is taking place at Westminster Abbey in London, where more than 2,000 guests are expected to be in attendance.
This is a stark contrast to the Coronation of his mother, Queen Elizabeth II, who was crowned in 1953, where 8,000 people were present.
King Charles and the Queen Consort will also travel a much shorter procession route than the late Queen.
