Cailin Russo is the 21-year-old model with the septum piercing and ludicrously pinnable style. She's had a pretty major last 12 months: starring in Justin Bieber's video for All That Matters (there were some inevitable rumours afterwards), shooting campaigns for US brands Mlle and OP, and last week, modelling Abercrombie & Fitch here at ASOS (check out her pics in the Abercrombie edit below). We grabbed her for a coffee (her order: green tea in an enormous mug) to chat beauty essentials, piercings and LA vs London style, in the ASOS canteen. All the glamour, babes.
