Teen fashion model and Kim Kardashian sister Kendall Jenner learned some important lessons at New York Fashion Week this year. 1) nepotism is a double-edged sword, and 2) fashion models are hungry and therefore mean! Reportedly, a gaggle of models without famous sisters put cigarettes in Kendall's drink backstage.

Per an NYFW "source" who spoke to In Touch:

The other models worked so hard to get a spot on the runway and didn't think it was fair that she was there. They started acting bitchy. Some even put out their cigarettes in Kendall's drink!

(At one show? All the shows? Unclear.)

Kendall has previously stated that being Kim's sister has absolutely not helped her land magazine covers, major fashion campaigns, and all the modeling jobs she's ever gotten. "People think that this [success] just came to me. But it didn't," she said. "What I have has almost worked against me."

Well, it's certainly working against her now. Pray for Kendall.
