2012 Celebrity Melbourne Cup Pics From Twitter & Instagram

There's no denying that the Melbourne Cup is one of the most hotly anticipated events on the social calendar, and with thanks to international guests such as Mischa Barton, Ashley Madekwe and Camilla, Duchess of Cornwall, today's celebrations look to be bigger and better than ever. Judging from years gone by, we can expect to see a lot of colour amongst the VIP guests, but thanks to social media we don't have to wait too long before the fashions on the field pics trickle in. So far we've spied Rebecca Judd sporting a Kerrie Stanley head-piece, Mischa Barton in bordeux Ellery and Kate Waterhouse looking lovely in lilac Gucci.
