There's been speculation for months about which of the young royals would be in Princess Eugenie's wedding and now with the affair mere hours away, we have our answer.
The Dean of Windsor will lead the service as he did for Prince Harry and Meghan Markle.
Here's the list of who else will be joining the Cambridge kids on Eugenie's big day.
"The Queen's precise arrival time of 10:52am."
An insider told New Idea, jealous Eugenie insisted Kate - who is looking as glamorous as ever following her return from maternity leave - entered through a side entrance, out of the main stream of cameras, in order to avoid the duchess taking away her limelight.
Eugenie's fiancé Jack has asked his brother, Thomas Brooksbank, to be Best Man. No "Pippa Middleton" moment for the York sisters.
Only a few Halloween face masks feature Eugenie's face, though some shopkeepers say that will change in the hours ahead of her wedding.
The traditional "to obey" has been omitted. And let's not forget their musical guests, including Andrea Bocelli, who will perform two pieces during the service, as well as the Royal Philharmonic Orchestra.
While the royal family is paying for the wedding itself, there has been disquiet among republicans and some newspapers over the security bill for the event, which has been estimated at more than 2 million pounds ($2.6 million), given that Eugenie does not carry out official royal duties.
Channel24, South Africa's largest entertainment website, will be providing live updates as the royal wedding day unfolds.
Their route will give the public gathered in the town a chance to see the couple following the wedding ceremony.
Finally, the bride herself will arrive and be led to the altar by her father Prince Andrew.
The other bridesmaids will be: Savannah Philips, seven, the daughter of Autumn and Peter Phillips; Isla Philips, six, the youngest of the Phillips' daughters; Mia Tindall, four, the daughter of Zara Tindall and Mike Tindall; Maud Windsor, five and goddaughter of Princess Eugenie, and daughter of Lady Frederick Windsor and Lord Frederick Windsor. This week, the members of the bridal party were revealed, confirming Princess Beatrice's role as Maid of Honour for her close friend and confidante.
They will then take an open-top carriage ride through Windsor, although it will be shorter than the one Harry and Meghan took in May when thousands thronged the streets and hundreds of millions worldwide watched on television. This route is more comparable to that taken by Prince Edward and Sophie on their wedding day. In the evening, guests will celebrate at a smaller evening reception at Royal Lodge, the York family home.
A second, festival-inspired party will follow on Saturday.
