Cara Delevingne is never one to hold back, so her message to doubters was exactly what you might expect. The supermodel and actress spoke to Time magazine from the set of Paper Towns about her struggle to land serious roles, practicing an American accent, a possible music album, the differences between modeling and filming and admits that she doesn’t know who she is. Oh, and she addressed the haters (because being on Cara’s level means having to deal with those who question your every move, natch).
