VIDEO : Nat Wolff Didn't Know Who His Paper Towns Co-Star Cara Delevingne Was

She is one of the most sought after models in the world, is friends with countless celebs and everyone just wants to have her eyebrows.
Pretty much everyone has heard of Cara Delevingne by now, everyone that is, except for her Paper Towns co-star Nat Wolff until just recently. At the New York premiere of his new film, Nat Wolff was totally honest about not knowing anything about his co-star except for seeing her on a billboard. He said, "I was the only human in the face of the Earth who didn't know who she was and then she walked in and I was like, 'I think I recognize you on a billboard outside my apartment in New York. I think I have walked my dog past you. She just blew us away, such a good actress and she is such a wild person."
