Kendall Jenner was reportedly bullied by other models at this year's New York Fashion Week.

Last week, the "Keeping Up with the Kardashians" star confidently strutted down the runway at numerous fashion shows of Marc Jacobs, Diane Von Furstenberg, Donna Karen and more. However, she was dealing with hatred behind the scenes.

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

Jenner also took to her Instagram account on Thursday to share a cryptic post seemingly hinting what she had to go through, quoting a famous line from teen comedy film "Mean Girl." "you can't sit with us," she wrote the following caption.

However, the skinny haters apparently did not affect the 18-year-old supermodel, as an insider told E! News: "If Kendall was bullied, she certainly isn't aware of it. She's too busy working hard and enjoying what she's doing."

The reality star previously discussed how hard it is for her to be taken seriously in the fashion world. "People didn't want to take a chance on me, I think because I was sort of known," she said in Teen Vogue's September issue. "They were a little bit on the fence about it. Some people might think that what I've done before made it easier for me to get jobs, but it was actually a disadvantage. I had to work even harder.

Similarly, Kendall Jenner admitted that she wants to get rid of her television image for her modeling career. "I want to be high fashion. I want to be taken seriously," she told LOVE magazine. "People think that this [success] just came to me. But it didn't. What I have has almost worked against me."

"I had to work even harder to get where I wanted because people didn't take me seriously as a model. Because of the show," she added. "I went on castings and some people weren't feeling me because of my name. But it was great when people didn't recognize me. I was like, 'Thank you. Please don't recognize me.'"
