They're the new "It" girls!

Kendall Jenner, Cara Delevingne, Gigi and Bella Hadid, and Hailey Baldwin were just a few of the handful of models and celebrities that went on a Karl Lagerfeld-hosted Chanel boat party down the Hudson River last night in NYC, and it looks like the bash was a complete blast!

We wonder how Kenny felt about her momager Kris Jenner being in attendance, though! It's got to be slightly annoying to have your mother tag along everywhere you go when you're trying to make a name for yourself, but the Kardashian matriarch seems to fit in with the cool crowd. The 59-year-old even took the opportunity to pose for pics with Katy Perry, who she previously spent time with at Paris Fashion Week.

"Yep @katyperry ...Lady Liberty is 100% photo bombing us!Best night in NYC! Thanks for an amazing night and dinner @karllagerfeld #bestnightever #Chanel #family," Kimmy K's mom captioned the below snapshot of herself and the pop star.

Fun fact - Paris Hilton DJ'd the event!
