Oh boy do we wish we had been a fly on the closet wall when Poppy Delevingne and Sienna Miller shared an apartment together in New York – imagine all of that boho beautifulness! The two gal pals were reunited last night in London, where they joined fashion designer Matthew Williamson and Sienna's fiancé Tom Sturridge at private members' club the Groucho. While Poppy kept things simple in skinny jeans, green boots and a brown suede gillet, her friend Sienna channeled full on hippy chic in wide leg floral trousers, wedges and a body-con top with her blonde locks styled in tousled curls.
The pair were papped locking lips outside the venue as they met and later Poppy posted a photo from the evening on Instagram with the caption: "Bigtimeboodlelove @siennaprivate me love you long time".
Meanwhile Anna Dello Russo has been enjoying a holiday with designer Stefano Gabbana on the volcanic island of Panarea, north of Sicily. While most of us spend our vacation in high-street swimwear, ADR's attire is of course far more appropriate to her style icon status - including half the Dolce & Gabbana Spring Summer 2013 collection. As well as Dolce bikinis and accessories, the star wore a RTW crop top and mini skirt for a jog along the beach front. As you do!
Speaking of swimwear, actress Gwyneth Paltrow is the perfect ambassador for Stella McCartney's bathers. In a photo on the Brit designer's Instagram, GP is seen jumping in a snake print two-piece - and showing off her enviable abs.
