All of the famous celebrities on Princess Eugenie's wedding guest list.

Princess Eugenie’s wedding is the next major occasion on the British royal family’s calendar, as her Majesty’s granddaughter is preparing to exchange vows with long-term boyfriend Jack Brooksbank on October 12.

But almost as exciting as the actual ceremony, is seeing the congregation of famous faces who are invited to these royal affairs.

At Prince Harry and Meghan Markle’s wedding in May, Oprah Winfrey, George and Amal Clooney, Elton John and the Beckhams were just a few of the very well-known faces who were in attendance.

So, who will be present at Princess Eugenie and Jack Brooksbank’s wedding? Here is a look at all the celebrities Princess Eugenie and her soon-to-husband are famously friends with.

Singer and Songwriter Ellie Goulding, and her partner Caspar Jopling – who are also recently engaged – are close friends with Princess Eugenie. They have often been photographed together at various events and have also been spotted going on double dates together at basketball games. We’re almost positive the ‘Love Me Like You Do’ singer will be attending this royal event.

However, earlier this month it was reported that a significant event for Kate Middleton's family may cause her to miss her cousin-in-law's big day. The Duke of Cambridge's sister, Pippa Middleton, is due to give birth in the same month of the wedding and, according to The Express, Kate would choose to be by her sister's side should her first child's birth fall on October 12.

Also in attendance at the ceremony will be representatives of charities the couple support, members of the Royal Household staff, the local community and school children from the Princess’ former schools.

Similar to Prince Harry and Meghan Markle, the ceremony will take place at St. George’s Chapel at Windsor Castle.
