John Green Discusses Cara Delevingne's 'Paper Towns' Movie Audition!

Cara Delevingne looks gorgeous in a shiny blue outfit while attending the J. Crew & Vogue London Fashion Week Party held at Winfield House on Tuesday evening (September 16) in London, England.

The 21-year-old model joined her gal pals Suki Waterhouse and Clara Paget at the party. She was also spotted out and about earlier in the day leaving her home in a casual outfit.

It was announced earlier that day that Cara will be starring in the upcoming movie Paper Towns, based on the novel by John Green.

“Cara Delevigne‘s audition blew everyone away (including me!) and she understands Margo profoundly. I am so excited!” John tweeted after the news broke. “(I should probably learn how to spell Cara‘s surname at some point.)”

FYI: Cara is wearing Emilio Pucci at the party.
