Princess Eugenie and Jack Brooksbank’s wedding guest list has just been released ahead of their royal wedding on Oct. 12.

According to Harper’s Bazaar, some of their guests are the same people that Prince Harry and Meghan Markle invited to their nuptials on May 19. Both royal couples chose St. George’s Chapel in Windsor Castle as their wedding venue.

George and Amal Clooney were reportedly given an invitation by Princess Eugenie and Brooksbank. George and Brooksbank work together at Casamigos Tequila in the United Kingdom, the actor’s alcohol company. Harper’s Bazaar is speculating on the possibility of George even serving the drinks at Princess Eugenie and Brookbank’s wedding reception just like what he did at Prince Harry and Markle’s wedding.

Ellie Goulding is good friends with Princess Eugenie and her older sister Princess Beatrice. The singer typically vacations with the royal siblings. With this, Goulding’s attendance at Princess Eugenie’s nuptials is almost guaranteed. And since she recently got engaged to Casper Jopling, he may also escort her during the huge event.

James Blunt and Sofia Wellesley have also been invited to Princess Eugenie and Brooksbank’s wedding. Wellesley's parents are Lord and Lady John Henry Wellesley so she has a connection with the royal siblings. Blunt and his wife were also in attendance at Prince Harry and Markle’s wedding.

Prince Harry’s ex-girlfriends-cum-friends, Chelsy Davy and Cressida Bonas, will also attend the royal wedding on Oct. 12. Bonas is close with Princess Eugenie so much so that they attended Prince Harry’s big day together with Princess Beatrice. Princess Eugenie was also the one that introduced her cousin, Prince Harry, to Bonas.

In related news, Princess Eugenie and Brooksbank also followed in Prince Harry and Markle’s footsteps by inviting 1,200 members of the public to attend their wedding on the grounds of Windsor.

“The attendees will view the arrival of the congregation and members of the royal family, listen to a live broadcast of the marriage service and watch as the bride and groom depart from St. George’s Chapel at the end of the ceremony,” a statement from the palace revealed.
