Supermodel Cara Delevingne made quite the splash at the GQ Men of the Year Awards in London Tuesday night. The 22-year-old rocked a Burberry coat, but once she took it off she looked smoking hot in her sheer black lace gown. From presenting to hanging with her BFFs Jourdan Dunn and Rita Ora, the model was the life of the party. And she caught everyone's attention when she tackled Scottish designer Jonathan Saunders and landed on the ground! Take a look at the pics of her tumble here!
