NYFW: Kendall Jenner is missing from New York Fashion Week, flies to Paris

With her best friends Gigi and Bella Hadid slaying the New York Fashion Week runway, we can't help but notice there's one supermodel missing. Where in the world is Kendall Jenner?

The second to youngest of the Kardashian clan, Jenner has been making quite the name for herself in the fashion world.

Since taking the runway in 2009, it's reported that she's amassed a nearly $18M net worth and was ranked as the highest-paid model in the world in 2017. Not bad for a 22 year old, who has walked for Victoria's Secret, Paris Fashion Week, and New York Fashion Week -- all many times.

Of course, all this stardom comes with a price.

While Jenner has been spotted at various fashion week events this year, including the Longchamp fashion show and on the red carpet at the Harper's Bazaar ICONS 2018, she has yet to be seen on the runway. It seems that the young model left NYFW prematurely, landing in Paris on Sunday evening.

According to various reports, Kendall decided to take this season off because of stress. "I try to keep myself cool. I go in and out of having freak-outs, so I just have to chill out and be by myself," she said in an interview before her Paris trip. "Yesterday, I took a bath because I was really stressing out. I lit some candles."

The model has been open about her anxiety before.

In an interview back in August, Jenner explained that she needed to take a step back from modeling because of her "debilitating" anxiety.

"I have such debilitating anxiety because of everything going on that I literally wake up in the middle of the night with full-on panic attacks. Where do I even start? Everything is so horrible, it’s hard to name one thing," she said in a Harper's Bazaar interview at the beginning of this year.
