Did Nat help Cara get the part in Paper Towns?

Paper Towns star Cara Delevingne, recently revealed that if it weren't for her co-star, Nat Wolff, she wouldn't be playing Margo. "I think it was really Nat that helped me get cast," she shares. "I don't think I would have gotten the part if I hadn't auditioned with him because we just got on really well. We spent the audition crying together. The director was like, 'Just improvise,'and we went off script and just cried and got really real and emotional and I think that's probably why I got cast." Well, we couldn't imagine Margo played by anyone else!
