Poppy Delevingne looked to be having the time of her life as she celebrated her 40th birthday alongside model sister Cara, Taylor Swift, Princess Beatrice and Eugenie.
The socialite dressed to impress in tiny purple sequin hotpants as she hosted the party at Hart pub before the celebrations moved onto an exclusive after-party at the luxury BoTree hotel in Marylebone.
Poppy, who turned 40 on Sunday, put on a very leggy display in the dazzling hotpants which she layered over opaque black tights and chunky boots.
Styling her blonde tresses in a waved half updo, the model added a dramatic purple fur coat to complete her birthday outfit.
Meanwhile her sister Cara, 33, cut a cool figure in a grey suit which she teamed with a striped white shirt and black striped tie.
The runway star carried a black briefcase during the evening and kept comfortable in a pair of white trainers.

Styling her dark locks loose, Cara completed her outfit with a pair of eye-catching orange tinted glasses.
The Paper Towns actress flashed a huge smile as she stepped out from the bash and gave a thumbs up to cameras.
With royalty rubbing shoulders with music megastars and fashion socialites, Poppy’s bash soon became one of the hottest celebrity parties of the year so far.
Leading the extraordinary guestlist was Taylor Swift who arrived hand in hand with her NFL fiance Travis Kelce.
Elsewhere pregnant Princess Eugenie, who is expecting her third child, looked in good spirits as she arrived with husband Jack Brooksbank.
Despite the problems caused by their errant parents Andrew and Fergie, her older sister Beatrice was also all smiles as she walked into the Hart pub with her spouse Edoardo Mapelli Mozzi.
Also seen celebrating with Poppy were Georgia May Jagger, Damian Hurley, Lily James, Alexa Chung, Isla Fisher, Nicky Hilton, Emma Weymouth and many more.
It comes after Cara looked worlds away from her former party girl days as she posted a series of pouty snaps.
The model and actor unveiled her super-glam new image as she attended the star-studded Academy Museum Gala in October.
Cara was famous for her party girl image in the 2010s, bursting on the showbiz scene as a model before making a foray into Hollywood.
But recently, the star has shown off her newly-glam Hollywood glow-up in an array of glitzy and elegant ensembles.
And the big occasion was no exception as Cara dazzled in a glitzy silver gown with a ruffled blue neckline for the gala.
Taking to Instagram, Cara shared a carousel of flawless snaps of her ensemble ahead of the event, where she was seen pouting at the camera.
She captioned the snaps: ‘@theacademy gala dump! Scroll through to reveal the truth behind the glitz and glamour.’

Earlier in the month, Cara looked less than impressed as she was forced to wait in line before entering the Stella McCartney show during Paris Fashion Week on Tuesday.
She rocked a black tank top and sunglasses as she stood with her hands on her hips while queuing behind a group of women.
Cara looked fuming as she pushed her way to the front and said: ‘Ok I’m just going to walk in, it’s getting crazy’.
However, things weren’t smooth sailing for the Suicide Squad star as security stopped Cara and asked for her QR code for entry.
One of her team informed the security guard ‘she doesn’t have one’ before Cara added, ‘this is just crazy’.
Eventually, the actress lifted up her sunglasses and asked, ‘Can I go in?’ prompting the security to finally recognise the star and reply, ‘Oh, sorry yes go in’.
Cara thanked the security before storming past, tucking a large black leather coat over her handbag and entering the building.
The star was later seen joining a different ‘guests’ queue where she patiently waited in line before eventually taking her seat on the front row next to Helen Mirren.
