Last week makeup artist Charlotte Tilbury hosted a makeup event (makeovers, forums, etc.) at Selfridge's in London. Throughout the week, many of her cool British pals — Kate Moss, Helena Bonham Carter, etc. — showed up at the department store in support. To close out the celebratory weekend, the spunky (and recently tatted) model, Cara Delevingne, stopped by to hang out wearing, in classic Cara streetwear, a baggy "90's" T-shirt and a sideways, flat-brimmed baseball hat. While she was doing typical model things like wearing a faceful of Charlotte Tilbury makeup and throwing peace signs and rock horns for fan photo ops, she also showcased her drum skills. Click to watch Delevingne take on a much more serious, less model-y look, as she jams out on a drum kit in the middle of the department store.
