Princess Eugenie and singer Ellie Goulding have been spotted on holiday together along with Princess Beatrice.
Victoria's Secret supermodel Karlie Kloss is another famous friend the princess has vacationed with. She is also very close with Eugenie's sister Beatrice.
Eugenie's fiancé Jack works with George Clooney on his Casamigo's tequila business, so it's highly likely George and Amal will be attending their second royal wedding of 2018.
Eugenie has remained friends with Chelsy Davy long after her split from ex boyfriend Prince Harry. The same goes for Harry's other ex, Cressida Bonas. Both ladies watched on as Harry tied the knot with Meghan, so it's likely they will be there to support Eugenie on October 12.
