She does look like an emaciated Christina Ricci at times.
I'm fascinated by her off-beat looks. At times she looks like a conventional Victoria's Secret model and then she abruptly does stuff like that! And that personality! And according to Wiki, in addition to modelling and acting, Delevingne also beatboxes, sings, and plays the drums and guitar.
Getting drunk with her would either be the most awesome experience or most awful experience, not sure which yet.
