2001 St Andrews
Kate Middleton catches Prince William's eye at St Andrews University, where both study art history. The pair are spotted out hunting together and have rooms close to each other in halls, facilitating manoeuvres of the "Can I help you with that Caravaggio essay, Kate?" variety. In the second semester, the future king pays £200 to watch Middleton modelling a black lace dress over a black bra and bikini bottoms in a charity catwalk show. Shortly afterwards, the pair become flatmates.
