Brooke Shields has broken the internet with a picture where she poses topless as part of the spring collection of denim label Jordache.

The stunning photo instantly reminded fans of another Shields' iconic ad, that of a Calvin Klein campaign shot more than forty years ago, when she was 15. At 56, the actress, model and activist has reflected candidly on her body in an interview with 'People,' looking back on that 1980 campaign that skyrocketed her popularity worldwide.

Shields opened up on the significance of the campaign and how her relationship to her body feels like these days.

"I appreciate it more now," Shields told 'People'.

"It's such an honor to be my age and be represented. I feel the magnitude of it more. There's a knowledge that comes with age, and this feels less like a job and more like a privilege," she continued.

Shields, more recently seen in Netflix holiday romantic comedy 'A Castle for Christmas', has also explained that it was crucial to her not to have her pictures retouched.

"It was important for you to see this is my 56-year-old body and to fight the retouching," Shields said of the shoot, styled by Deborah Watson.

"I'm always like, 'You better keep it honest.' And we did," she added.

Shields then weighed in on Jordache's famous slogan, reciting "You've got the look", and how it has been groundbreaking.

"'You've got the look' was iconic," Shields said of the ad slogan.

"Everybody was like, 'Well, I want the look. You've got it, so I want it.' Jordache was very much a part of that barrier-breaking mentality. They celebrate the idea of being sexy and bold and they've always featured strong, hard-working, ambitious women in their campaigns. It was never just about models. I've always appreciated that – it celebrates a different type of advertising and puts the focus on female strength," she added.

How Shields Prepared About Going Topless For Jordache

When it comes to losing her top for the pictures, Shields explained that she trusted photographer Cass Bird, who shot the Jordache campaign.

"I knew Cass [Bird] would handle it well, and I also knew it wouldn't be exploiting at all," she said.

"There's something about owning your sexuality at this age that is on point for where we are today. It's not angry empowerment."

Shields admitted she had trained leading up to the photoshoot, working with personal trainer Ngo Okafor.

"We did 5 a.m. workouts, but I wasn't drinking so it was easier to wake up in the morning," she shares, adding, "I pushed it to the limit. My ego helped! I thought, "If you do these pictures, and you are not happy with what you see, you'll be hard on yourself."
