Poppy Delevingne's hen-do certainly didn't disappoint — click on the photo below for HELLO! Online's gallery of the best moments.It was tipped to be a star-studded evening full of fun and frolics and
Cara Delevingne's big sister bid farewell to singledom with a dazzling 90s themed party in London with a guest list that included Alexa Chung, Sienna Miller, Georgia May Jagger, Laura Bailey, Nick Grimshaw and Harry Styles.
The party got into the spirit of the occasion with bride-to-be Poppy channelling the character Alabama from the film True Romance, Sienna dressing up as Patsy from Ab Fab, Nick and Harry as two thirds of 90s boyband Hanson.
They wore custom-made printed t-shirts by Black Score, which had been exclusively designed for the event.
Celebrations involved personalised fairy cakes and sweets at the Ivy, drinks at the Groucho Club and dancing at the Edition Hotel's basement club.
The well-connected group shared lots of snapshots from their wild night on Instagram using the hashtag #popdoghen.
Poppy, 27, is marrying her long-term beau James Cook. She announced their engagement on her Twitter page last October.
James, who has been with Poppy since 2007, proposed with a bespoke box from Anya Hindmarch. He presented her with a red leather jewellery box with photos of the couple, two little drawers thought to contain a ring and the words 'Will you marry me?' embossed across the inside lid.
Poppy captioned the shot, "Errr YES… #happiestdayofmylife."
"It all feels pretty surreal at the moment, but I'm truly over the moon," she told VOGUE shortly after he popped the question. "Even though we've been going out for almost five years, the proposal was such a surprise; I practically fell off my chair."
