Instead of Buckingham Palace stage managing the event with its usual military precision, US gossip site TMZ has controlled the narrative with scandal after scandal.
Princess Diana's former bodyguard says a lone attacker is the biggest security threat to Prince Harry and Meghan Markle's wedding.
His Royal Highness and his Hollywood actress fiancee are set to tie the knot tomorrow at Windsor Castle. They cannot marry at the favoured venue of the royal family, WestminsterAbbey, because Markle is a divorcee.

Ken Wharfe, who served as a royal protection officer for 16 years, told NZME he was pretty confident the wedding would be go off without a hitch, but if there was to be a security incident it would be "from a lone, fixated individual that wants to make a statement".
"We've seen this in the past - you know, the naked runner or somebody who chooses to through something or make a rush towards the carriage. These are the real problems - more of an embarrassing factor than anything else."
Thames Valley police and the Metropolitan police, who are responsible for security at the wedding, would have been preparing for the big day since Prince Harry and Markle announced their engagement at the end of last year, he told Newstalk ZB's Larry Williams.
Security would be tight and all the guests would be searched and vetted before they could set foot on the castle grounds.

The biggest risk would be when the newlyweds left the castle for a procession through Windsor town in an open horse and carriage.
The route they will take is lined with businesses and residential properties and security personnel would have searched each building and spoken to each homeowner before the wedding.

"Since William and Kate's wedding a lot's happened internationally. We have this rise of terrorism, so there's a lot more work to be done," said Wharf.
"But I'm pretty confident that with [the police's] expertise I think the country and the world can expect a happy day.
"I'm not suggesting or saying that it will be 100 per cent, no security operation ever is, but with the expertise we can expect there to be, in my view, a very, very closely co-ordinated security operation."
Wharfe also weighed in on what he believed Princess Diana would think of Markle and Prince Harry's union if she were alive.

"I think that it's very frank that it's irrelevant really that he's marrying somebody of mixed race and American and a divorcee," he said.
"I think [Princess Diana] would be absolutely delighted on the proviso that her son was happy and it clearly looks like to me - and I haven't spoken to him for a few years - that he seems to be very happy and if that works I can't think of a better combination."
Tomorrow night nzherald.co.nz will have the latest coverage of the royal wedding as it happens. The wedding will begin at 11pm tomorrow (midday UK time).
