Why you should follow: If you've seen any of Burberry's recent ad campaigns, then you should be familiar with Cara Delevingne. We recently named her one of the 21 hottest models under 21 but maybe we should've also called her one of the coolest. Her Instagram will show you that she went to The Watch The Throne Tour twice, she's good friends with female rapper Azealia Banks and she doesn't take herself too seriously.
