That Time Cara Delevingne Took the Paper Towns Cast on an Impromptu Water-Park Adventure

Paper Towns is the latest John Green novel to get the big-screen treatment, and the author stopped by our LA studios with stars Cara Delevingne and Halston Sage to talk about why he's glad to "let go" of his books once they're written. We also talked with the trio about the books and authors they fell in love with in high school, and they played a senior-superlatives-inspired game of "Most Likely To." Watch to find out who they think would have been nominated most likely to become president . . . and which of the three said they'd probably have been voted most likely to kill someone. Paper Towns hits theaters on July 24.
