Hailey Bieber has revealed the real reason why she doesn't appear on the runways anymore. The model, who has graced catwalks for major fashion houses across the globe during her career including Versace, Off-White, and Dolce & Gabbana, shared that her decision to step back from certain aspects of the industry was made because of one comment made by a casting director.

"I had a really bad experience with a casting director who was very important," Hailey told Allure.

"He said something to my agent that just shook my confidence when it came to the runway. I don't want to feel bad about myself in this space because I feel really good about the other work that I do. So why would I even put myself in a position to feel small?"

In the same interview, Hailey spoke about finding a balance between her modeling career and life as an entrepreneur — given how she's just launched her skincare line Rhode, which is inspired by her mother and grandmother.

"I just could always remember my mom, as a child, getting (me) out of the bath, drenching me head to toe, just hydration, hydration, hydration, very focused on keeping the skin healthy. It started with my grandmother, she taught my mom, my mom taught me," said Hailey, when asked what inspired her to start a skincare line.

She then revealed that it took a lot of time to develop products, which included market testing as well.

"I was ordering crazy amounts of skincare, trying everything that was expensive to inexpensive to mid-range. And I found that the most tried-and-true stuff were the solidly formulated products that were affordable, where I could tell people kept on going back to, and that's what I kept going back to as well. The initial launch focuses on maintaining the skin's moisture barrier. I've given it to a lot of different makeup artists to try on their clients and I've gotten really good feedback on it," she said.

But, she's not too worried about the competition in the market, with several celebrities now boasting of their own beauty line, she added.

"I think that as a team, we are going into it knowing that people are tired of seeing brand after brand after brand from different people and faces and celebrities," Hailey added.

"I definitely have had my fears, for sure, because the market is so busy and so saturated. And I've had to, obviously, have the confidence in myself and in our brand to really feel it's going to be something refreshing and different."

Her interview comes after a recent health scare, where the model experienced stroke-like symptoms following a clot in her brain, according to People.

"They found I had suffered a very small blood clot to my brain, which caused a small lack of oxygen, but my body had passed it on its own and I recovered completely within a few hours," she shared in an update on her social media.

"Although this was definitely one of the scariest moments I've ever been through, I'm home now and doing well, and I'm so grateful and thankful to all the amazing doctors and nurses who took care of me!"

Thankfully, Bieber has recovered well since the incident.
