It's not long to go until Princess Eugenie and Jack Brooksbank tie the knot in the second royal wedding of 2018.
And as the big day gets ever closer, it looks like this could be the most star-studded event of the royal calendar, yes even more than Harry and Meghan's nuptials.
Seeing as the ninth-in-line to the throne and her fiance have a bevvy of famous friends, some big celebrities are expected to fly into Windsor for the October wedding. But aside from the obvious royal family members, who else will be in tow?

George and Amal Clooney
The A-list couple literally shone at Harry and Meghan's wedding and they're expected to make another trip to Windsor as Jack Brooksbank works with George Clooney's tequila business, Casamigos.
Rande Gerber and Cindy Crawford
Rande Gerber is also a partner in Casamigos and his supermodel wife will no doubt accompany him.
Prince William also had a massive crush on Cindy in his youth and Princess Diana gave him the shock of his life when she invited the supermodel to Buckingham Palace for tea, so this should make for a fun reunion.
The British songstress is tight with the young royals- not only did she reportedly sing Prince William and Duchess Catherine's first dance song, but she also "had a thing" with Prince Harry and is a close friend of Eugenie's and her sister, Princess Beatrice. Ellie and her now-fiance, Caspar Jopling, double dated with the future Mr and Mrs Brooksbank at a basketball game in New York last year.

Despite splitting with Harry in 2011, Chelsy has remained close with members of the royal family. And seeing as the Zimbabwean-born beauty attended her ex's wedding, we doubt this is too scandalous.
Like Chelsy, the actress and socialite is a good friend of Princess Eugenie's, in fact, the bride-to-be introduced Harry to Cressida. Cressida was also a guest at Harry and Meghan's wedding so it's clear she's still in the fold too.
James Blunt and Sofia Wellesley
The You're Beautiful hitmaker and his aristocratic wife love to hit the festival scene with the princess and even attended the Sentebale Concert at Kensington Palace in 2016.
James Blunt, who served in the British army with Prince Harry and performed at the Invictus Games in 2016, also attended the prince's big day when he married Duchess Meghan in May.
David and Victoria Beckham
It wouldn't be a royal wedding without King and Queen Beckham!
Not only did David and Victoria attend both William and Harry's respective weddings, but their daughter Harper even celebrated her sixth birthday at Buckingham Palace and Eugenie's dad, Prince Andrew, footed the bill.
Some other potential guests include models Kate Moss, Cara Delevigne, Suki Waterhouse and Karlie Kloss, the latter of whom accidentally let slip Princess Beatrice's secret Instagram account.
