The gorgeous twosome, Poppy and Cara Delevingne, glammed up the muddy proceedings in their All Saints clobber.
'Wear a cap!' Cara said when we asked for her festival tip. 'Mine's from New Era and it's handy for when it's raining, although then you get hat hair...' And Poppy's words of advice? 'A slick of red Chanel lipstick means you don't have to wear any other makeup,' she said.
Speaking about festival disasters, Poppy told us: 'When I was at Glastonbury last year, one of my boots got stuck in the mud and I fell flat on my face, but I just had a few ciders and got on with it.' Oh cripes!
You wouldn't get that at Coachella, eh? 'Exactly,' she agreed. 'Kate Bosworth is my festival style icon and every year she looks so effortless at Coachella'. True dat.
Poppy and Cara were joined by older sister Chloe too so it was, in fact, a Delevingne triple whammy. 'We all travel so much so we're never in the same place,' Poppy said. 'But today is our grandmother's 100th birthday so we've been having a day of family celebrations. We ate lots of cupcakes and went through old pictures of her - it was really interesting to see where Cara gets her eyebrows from.'
Oh, to be a Delevingne...
