Poppy Delevingne's Hen Do: Sienna, Cara, Alexa &Amp; Harry Party At London's Groucho Club

Poppy Delevingne saw off singledom in style as she partied with showbiz pals at the Groucho Club in London on Saturday night.

Cara Delevingne's sister enjoyed a right old knees up for her famous blondes-themed hen do alongside mates Alexa Chung, Sienna Miller and, er, Harry Styles.

The bride-to-be was channelling her inner Alabama Worley from the flick True Romance, while model mate Laura Bailey dressed up as Cher Horowitz and lil' sis Cara went as Twiggy.

One Direction babe Harry Styles and his bosom buddy Nick Grimshaw threw on a couple of blonde wigs and declared themselves two thirds of Hanson.

Poppy and Alexa were spotted making tracks in the early hours of the morning looking like they'd thoroughly enjoyed themselves.

Fortunately Pops threw a cosy leopard print coat over her bra and mini skirt combo so she wouldn't catch her death, although just looking at her's and Alexa's bare legs is enough to make us shiver. Brrrr.

Check out all the snaps from Poppy's sendoff in the gallery below... Bonus points if you can guess who everyone was meant to be dressed as!
