Jenner supports Cara Delevingne at 'Paper Towns' premiere

Kendall Jenner and sister Kylie Jenner supported Cara Delevingne at the Paper Towns premiere Saturday.

The teenage American reality stars showed their love for the 22-year-old English model and actress at the film's Los Angeles premiere and got silly with Delevingne at the after-party.

Kylie Jenner shared a video of herself and Delevingne performing a racy synchronized dance at the fête, writing, "These didn't make it to Snapchat so here you are Instagram."

Paper Towns is based on the John Green novel of the same name, and opens in theaters July 24. The author attended the premiere and posted a photo of himself with Delevingne, Nat Wolff and other cast members on Instagram.

Kendall Jenner and Delevingne are both known for their work with Chanel, and have also walked the runway together for Fendi. Kylie Jenner, meanwhile, recently posed with her elder sister for a sisters-themed Balmain campaign featuring Gigi Hadid and Bella Hadid.
