Cara Delevingne, Karlie Kloss hit 'Paper Towns' premiere with siblings

The best accessory at the Paper Towns premiere in New York City was a brother or sister: just ask supermodel Karlie Kloss and the film's stars Cara Delevingne and Nat Wolff, whose siblings played supporting roles on the red carpet. Leading the sister act was Cara's fashionable family member, British model Poppy Delevingne, while fellow supermodel Karlie arrived with sis Kimberly Kloss.

Karlie's 20-year-old sister could have easily been mistaken for a supermodel as well as Kimberly stood alongside Karlie, who recently launched 'Klossy,' her vlogger channel. The blonde beauty received plenty of attention from photographers as she arrived with her famous sister.

The two were spotted laughing and catching up with Cara, before taking a selfie with her and Cara's co-star Nat Wolff – who just happened to count on support from his younger brother, former Naked Brothers Band member Alex Wolff.

Alex, who is the spitting image of his big brother was happy to join him at the premiere. "It's always hard separating," he told HELLO!. "I was doing a movie in Virginia, and he was filming in North Carolina, so that was pretty sad when we weren't together. But we got to do a song for the soundtrack, and we got to reunite so that was great."

HGTV's Property Brothers Drew and Jonathan Scott also spent the evening together taking in the film adapted from John Green's book.

The film marks an exciting move for Cara, who has never hidden the fact that she would like to leave the modeling world to pursue a career in acting. Paper Towns sees her starring in her first leading role, and the star is now focused on success in Hollywood.
