Jamie Lee Curtis said her topless scene in the 1983 film Trading Places made her feel "embarrassed."
The Halloween star played sex worker Ophelia in the hit comedy, which also stars Dan Aykroyd and Eddie Murphy. The film focuses on a wealthy commodities broker (Aykroyd) who inadvertently switches lives with a blue-collar worker (Murphy).
"I was 21 years old and the part required Ophelia to take off her dress," Curtis told People in a new interview. "Did I like doing it? No. Did I feel embarrassed that I was doing it? Yes."
"Did I look OK? Yeah. Did I know what I was doing? Yeah. Did I like it? No. Was I doing it because it was the job? Yes," the actress continued.
Curtis went on to say that doing a nude scene at her current age would be "the last thing in the world I would do now."
"I wouldn't do it today, it's the last thing in the world I would do now. I also am married for 37 years, I wasn't married then. I'm a mother of children. Absolutely not," the Freaky Friday star added.
Curtis has long been an honest voice in Hollywood, last year opening up about what it's like aging whilst still appearing on the silver screen.
Back in October, Curtis appeared on the British morning show Lorraine, and said she's been a long-time advocate for natural beauty after succumbing to plastic surgery in the past.
"I have been an advocate for natural beauty for a long time, mostly because I've had the trial and error of the other part," she said.
"I did plastic surgery — it didn't work. I hated it. It made me feel worse. I tried to do everything you can do with your hair."
"Personally it felt humiliating. I would go into the nail salon, the smell of the chemicals, the feeling of that color on my hair, the wearing the thing, sitting under the hairdryer. I was like, for what?"
Curtis has certainly experimented with her hair over the decades - going from brunette to a long blonde hairdo, before finally landing on her signature short cut.
"Very early on in my career, I had a perm and then had to dye my hair for a movie and it burned my hair off my head," she explained.
"The first time I cut my hair short, I went, 'Oh! Oh my god. Oh, wow. I look like me.'"
Since then, she's also stopped dying her hair brown — pivoting away from her iconic look made famous in 1994's True Lies, alongside Arnold Schwarzenegger.
"I've also been an advocate for not f***ing with your face," Curtis added. "And the term 'anti-aging.' What? What are you talking about? We're all going to f****ing age. We’re all gonna die. Why do you want to look 17 when you're 70? I want to look 70 when I'm 70!"
