Britain's Princess Eugenie and Jack Brooksbank leave Windsor Castle a day ahead of their wedding in Windsor, Britain, on Thu., Oct. 11, 2018. According to reports, the official "I dos" will happen at around 6am ET.
The royal family have also arrived.
"And I think that for Princess Eugenie of York, who lives after all just up the road with her father at Royal Lodge, it's the local place". Be sure to tune in below to catch the festivities as they happen live.
The BBC will also show highlights later in the day, but decided against live coverage of the wedding. The invitation list stretches to 850 guests - 250 more than Meghan and Harry.
Princess Eugenie arrives for her wedding to Jack Brooksbank wearing the Greville Emeral tiara.
Princess Eugenie, the granddaughter of Queen Elizabeth II, is set to marry tequila company executive James Brooksbank on Friday morning, but the second royal union of the year seems to have less interest than Prince Harry and Meghan Markle's May celebration.
But Eugenie, who is not a working royal, and Jack will not head up the Long Walk like Harry and Meghan, but take a shorter route back to the castle. The couple will proceed along the High Street and return to Windsor Castle through Cambridge Gate - a move which echoes the Earl and Countess of Wessex's nuptials.
Eugenie has worked for several years in a fulltime position with the Hauser and Wirth art gallery in London.
While Harry's wedding featured a fiery sermon from a US Episcopalian bishop and a gospel choir, Eugenie's will be more traditional with a performance by Italian tenor Andrea Bocelli and the address given by Conner.
The queen will then host a reception for the couple and their guests at the castle. It has criticized the royals for using weddings as "PR exercises" and expecting taxpayers to pick up part of the tab. "A lot of tourists don't even know about this wedding Friday, but it will bring in the crowds and should be a good day for us".
