Duke University porn star Belle Knox is known for talking about how X-rated films make her feel powerful, but as it turns out, it looks like all great things come with a price.

Belle Knox Reveals An Awkward Moment

On Tuesday, Salon posted a clip from Knox's documentary called "Becoming Belle Knox" where the actress discusses the consequences she's had to face with her choice to star in adult films. Knox, whose real name is Miriam Weeks, revealed that a lot of her family doesn't speak to her anymore and she's lost her best friends because she joined the sex industry. She also mentioned how doing porn can make her feel less happy.

"Being in this industry has a way of making you very cynical and very bitter," she said. "And I feel like in a way I've already started to get kind of a bit bitter and a bit cynical. It teaches you to be street smart and not to trust people."

Belle Knox Dishes On Who She Was In High School

The actress then revealed a rough story on how she doesn't always get told on who she's doing scenes with until she can't back out of it. One time, she found out that her co-worker was 50-years-old and if she didn't go through with it, then the company would never hire her again.

She also said that other girls in porn have called her a "brat" and told her that she should do the scene even if her boundaries are disrespected.

"I felt like crying during the entire scene," Knox admitted. She also let out some tears as she talked about how sad her mother would be if she knew her daughter was doing this.
