Get your fancy hats ready, y'all, because the countdown to Princess Eugenie and Jack Brooksbank's wedding date is on [1]. The British royal and her commoner fiancé [2] are set to tie the knot on Oct. 12 at St. George's Chapel in Windsor, England, the very same place where Prince Harry and Meghan Markle married [3] earlier this year.

Princess Eugenie and Jack's expensive wedding [4] is expected to be a star-studded affair, possibly drawing guests like George and Amal Clooney [5] — Jack works with George's tequila brand, Casamigos — and David and Victoria Beckham [6], who are longtime friends of the royal family. Two people who may not be in attendance, though, are Kate Middleton, whose sister, Pippa, is expecting her first baby in October [7], and Eugenie's grandfather Prince Philip, who reportedly has a strained relationship with Eugenie's mother [8], his former daughter-in-law Sarah Ferguson. We'll have to wait until Oct. 12, though, to see if either royal is in attendance for the big day.
