Kendall Jenner unrecognized at Marc Jacobs show, until she shows off her chest
{{#rendered}} {{/rendered}}Kendall Jenner became a real fashion model at New York Fashion Week on Thursday, but at first, nobody even noticed.
"Kendall was unrecognizable. No one backstage knew who she was," an insider told FOX411. "The photographers and backstage press ignored her."
The 18-year-old reality starlet bared her chest when she walked the runway for the Marc Jacobs show. Sporting a short wig and severe makeup, Jenner walked the catwalk in a completely see-through long sleeve V-neck sweater, sans bra.
{{#rendered}} {{/rendered}}Our source said that backstage before the show, Jenner was "relieved that no on recognized her. She liked the fact that nobody could tell it was her."
"Kendall didn't seem to want the attention," the source continued. "Back when Paris Hilton did runway back in 2000, 2001, that's all she cared about–people fawning over her backstage. Kendall was the opposite–a pro."
For the show, Jenner's normally dark eyebrows were covered with light makeup, giving her a creepy no-eyebrows look on the runway.
{{#rendered}} {{/rendered}}As with the last time Jenner showed her chest -- in a modeling photo she posted on Instagram a couple weeks after her 18th birthday showing her in a sheer top sans bra -- her older sisters were quick to turn to social media to voice their excitement and support of their younger sister.
“My baby sister killed it today walking in the Marc Jacobs fashion show!!! Kenny you are so dope…” Khloe Kardashian tweeted.
She responded to her sister’s critics, stating the Jenner didn’t choose her own wardrobe for the runway.
{{#rendered}} {{/rendered}}“Its [sic] a fashion show. She doesn't choose!” Khloe wrote in response to one user who declared that young Jenner “needs to cover up.”
Kim Kardashian, who memorably posed for Playboy, also chimed in.
“Proudest sister ever!!!! @kendalljenner I love watching you live your dream! #MarcJacobs #NYFW,” she wrote.
{{#rendered}} {{/rendered}}Our insider said in the fashion world, Jenner's Thursday show was a big deal indeed.
"Some people would say that this was stunt casting by Marc Jacobs, but to me Kendall Jenner walking in Marc Jacobs absolutely legitimizes her as a model," the source said. "She was sweet and unassuming. I don't know if she walked the show on her own merits or because of who her family is, but if she got this on her own, that's something to be proud of. For the models, they're very excited to walk Marc Jacobs. It's a big deal."
