Kendall Jenner made her Milan Fashion Week debut on Thursday, September 18. The 18-year-old reality star, who uses her first name for her modeling career, rocked the Fendi fashion show for their Spring/Summer 2015 collection.

The "Keeping Up with the Kardashians" star sported a graphic sleeveless tee with rips through it, paired with brown suede harem-style trousers. Kendall, who wore a bright blue eye make up, completed her look with matching strappy heels and shiny bag.

She walked the runway show, which featured the latest collection from Fendi's creative director Karl Lagerfeld, along with supermodels Cara Delevingne, Georgia May Jagger, Joan Smalls and Binx Walton.

Between her shows, Kendall posted a fun backstage picture with a fellow model which was presumably a response to recent rumors which said she was "bullied" by other models during the New York Fashion Week. She captioned it with a famous line from "Mean Girls", "You can't sit with us."

A source previously told 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. Some [of the models] put out their cigarettes in Kendall's drink! They thought she was getting special treatment and just weren't OK with it."

Meanwhile, another source told E! Online, "If Kendall was bullied, she certainly isn't aware of it. She's too busy working hard and enjoying what she's doing."
