This could be why Kendall Jenner didn't appear on the runway at New York Fashion Week

Kendall Jenner's career has skyrocketed over the past few years, following her introduction to modelling back in 2009. She showed everyone who doubted her as 'just a reality TV personality' that she was a seriously talented model and has seen great success.

Despite appearing on over 89 runways in her career so far, we didn't see much of Kendall at this year's New York Fashion Week. Why? Well, Kris Jenner might have revealed the reason in the latest teaser from Keeping Up With The Kardashians.

The video shows Kris on the phone to Kendall, who called her about an "emergency", which it's revealed is a panic attack, while she's in LA. Kris explains,

"She doesn't feel well, she's not sure what it is..."

She then says to the camera,

"Kendall struggles from anxiety, and I think she has so much going on that she gets herself really worked up. Kendall gets the most anxious during fashion week so when she's travelling a lot. And Milan's coming up and trying to juggle it all is overwhelming."

In flashback footage, Kendall reveals that she gets "light-headed" and feels like she's "going to faint" and even though she looks fine, she doesn't "feel fine".

Kendall did appear on one runway at Milan Fashion Week in January, where she came under fire for wearing what looked like a real fur coat, although neither the brand or the model have confirmed this.

She also attended the Off White x Jimmy Choo dinner in New York City and spent some time behind the camera with the Adidas Originals crew, but hasn't been spotted on the runway - maybe she just needed to sit this one out to focus on her health. Either way, we hope she's feeling better.

If you or someone you know is suffering from anxiety or panic attacks, visit the NHS website for advice.
