Despite the months of meticulous planning and preparation that went into King Charles III's Coronation on Saturday, there were a few mishaps along the way.
All eyes were undoubtedly on King Charles and his wife Queen Camilla as they were crowned in Westminster Abbey during a two-hour historic service that followed long-standing protocol from centuries before.
However there were some key figures among the 2,000-strong crowd that ended up distracting viewers and unintentionally stole the show.
From the Princess Royal's extravagant feathered hat blocking Prince Harry's view to Katy Perry causing a scene trying to find her seat, we take a look a the most awkward moments of the royal occasion that will likely be remembered in years to come.
Katy Perry's confusion
Among the celebrity guests was US pop singer Katy Perry, who is set to perform in the Coronation Concert on Sunday evening, along with the likes of Lionel Richie.
But Katy, dressed in a striking baby pink number, left fans in stitches for the wrong reasons at the ceremony on Saturday.
On her way into Westminster Abbey, she almost fell to the floor as the heel on her white court shoes almost gave way.
And then once inside the abbey, walking alongside British Vogue editor Edward Enninful, the California Gurls star struggled to find her seat among the crowd.
Puzzled Katy sought help from guests already seated as she roamed the pews asking which was her spot.
She later broke her silence a few hours later, tweeting: "Don't worry guys I found my seat".
Boos for disgraced Prince Andrew
One member of the royal family had a not-so-pleasant response from the crowd ahead of the ceremony.
The King's disgraced brother Prince Andrew was booed as he was driven past royalists down The Mall.
The Duke of York faced the wrath of some onlookers who vocalised their distaste for him from the grandstand in front of Buckingham Palace.
Although he did attend the service, there was no special role for the Prince.
Anne's hat
Prince Harry arrived at his father's big day solo as his wife Meghan Markle remained in California to look after their children and to celebrate Archie's birthday.
But the Prince might have had a better view if he'd stayed put, as Princess Anne's extravagant hat ended up obstructing his view.
The Duke of Sussex was sat in the third row, alongside Princess Eugenie's husband Jack Brooksbank and Princess Alexandra - the cousin of the late Queen who hasn't had a working royal engagement in a decade.
Once the ceremony commenced, viewers began to notice that poor Harry's face was being blocked by the red feathers, with some cheeky commentators audaciously suggesting it may have been done on purpose.
'Cocky' bravado
Despite not having a great viewing, Prince Harry reportedly performed a display of "cocky bravado" as he arrived at the ceremony, according to a body language expert.
The estranged Prince used his controversial appearance to signal to the world that he was "happy to be back" on UK soil after months of attacks on the royal family amid escaping to the US for a new life with Meghan.
Body language expert Judi James told The Mirror that viewers witnessed "an incredible return of the joker prince" as a grinning Harry arrived alongside royal cousins Princess Beatrice and Princess Eugenie.
Eerie guest
There was one potentially unwelcome guest at Westminster Abbey - a 'Grim Reaper'.
The spooky figure, donning the mythological character's iconic dark robes whilst carrying an item resembling a scythe, was filmed walking by the doors of the abbey.
Creeped-out royal fans immediately took to Twitter to share screen grabs of the dark silhouette.
Another pen incident
King Charles was stuck in an awkward mishap with a fountain pen once again after last year's fiasco in Belfast.
When it came to singing the oath in the abbey, it seemed the pen wasn't working as intended amid the important declaration.
Charles could be seen grimacing as he placed the lid back on top of the stationery item.
The monarch is known to carry his own pen for when he is frequently asked to sign visitors' books during royal visits, but it seems the item has been letting him down lately.
An unsteady fit for the Queen
Camilla's family proudly looked on as she was anointed following Charles - but her incredible crown might not have been the best fit.
The new Queen was filmed using her index finger to adjust her hair underneath the crown at least five times.
She then raised her hand and appeared to give the Archbishop of Canterbury some verbal assistance.
It came after the Archbishop was forced to spend several seconds adjusting the crown on the King's head.
Prince Louis and the National Anthem
While all eyes were on the King and Queen, at points during the ceremony it was Prince Louis that stole the show.
The five-year-old royal distracted viewers first by yawning and fidgeting, before accidentally singing 'God Save The Queen' for the National Anthem when the service came to an end.
There was also confusion when the young prince appeared to go missing from the ceremony and wasn't seen next to his parents, the Prince and Princess of Wales.
He did process into the abbey with his family - but due to still being young, he was "retired" during the service due to his tender age.
Officer fainting
More than 4,000 ceremonial troops took part in the procession escorting the new King and Queen back to Buckingham Palace in the historic Gold State Coach.
However unfortunately just moments before the procession kicked off, a Royal Navy officer dramatically fainted.
A small number of military members rushed to assist their colleague who was quickly put onto a stretcher and given medical assistance.
