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.

Just like Prince Harry and Meghan Markle's wedding, George and Amal Clooney could very likely appear at the royal wedding ceremony in October. Princess Eugenie's fiancé is the UK ambassador for Casamigos tequila, which is a spirit company co-founded by George.

Cindy Crawford's husband Rande Gerber also co-founded Casamigos, so they may also have received an invite.

The Beckhams have attended two royal weddings so far and hence our guess is that they will be invited to a third. The family evidently has close ties with the royals, with their daughter Harper celebrating her sixth birthday last year at a tea party at the Queen's residence, Buckingham Palace. Just casually.

Cara Delevingne is a possible attendee, with Princess Eugenie and the international model being spotted leaving a few parties together over the years.

Kate Moss, Suki Waterhouse and Naomi Campbell are also all friends with Princess Eugenie, according to Harpers Bazaarand are all reported to have been invited to the nuptials.

Sir Elton John and James Blunt also share close connections with the Royal family, and hence are similarly expected to be attending.

As well as close friends and family, the couple are inviting 1200 members of the public who will be selected through a ballot system, akin to the one used at the Duke and Duchess of Sussex' nuptials in May.

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.
