Despite St George's Chapel only being able to hold 800 guests, Princess Eugenie has reportedly invited 850 - meaning that extra chairs may need to be brought in. No doubt Princess Eugenie's nuptials will have just as many celebrity guests.
"Whilst Meghan and Harry's wedding was an global spectacular, Eugenie and Jack will be having a more homely occasion celebrating the best of Britain, but with an equally star studded guest list".
The wedding of Eugenie, 28, who is set to get married on October 12, will cost around £2million, a smaller bill than the eye-watering one issued for Harry and Meghan, which amounted to £45million.
But the royals are not holding back on celebrations for their second big wedding of 2018. The 400-person black-tie reception at Royal Lodge, thrown by the Duke of York and his ex-wife, Sarah Ferguson, will take place later that evening, but that's not even the final affair.
According to United Kingdom publication, The Sunday Times, Armstrong-Jones is also organising a "festival and funfair" themed party in the grounds of the Royal Lodge, which will include "dodgems and funfair rides, coconut shies, lots of food stalls, loads of cocktails, bloody Marys for the hangovers and a festival vibe".
The Royal Lodge could also become the setting for a private concert, taking things up a celebrity notch from Meghan and Eugenie's weddings, according to a source.
Some of the people who could be left in the standing room only section reportedly include some crossover guests from Harry and Meghan's wedding, like George and Amal Clooney, David and Victoria Beckham, Robbie Williams and Ayda Field, and Tracey Emin, according to the Daily Mail. Philip and Sarah will be in relatively close proximity to each other and Sarah's very nervous about it.
"People have been giving her some friendly advice". The only difference so far is that Eugenie is apparently making some tweaks to her special day - and those changes will ensure her wedding is bigger.
