The actress and model, 57, shared an Instagram post last week, where she posed nude on the edge of a bed covered by just the white sheet she held against herself. Detailing in the caption of her post that she was looking to share some "food for thought," Porizkova continued, "Is it objectification or celebration?" "In a patriarchal society, women have always been seen as objects of desire or nurture. Because these are the needs of men who run the world," she added. "This is why youth and beauty are such a strong currency."

Porizkova wrote, "She is taking the powers she has been given and using them in her own interest but is simultaneously helping to perpetuate a system which has always existed. For this she will be shamed and celebrated by both the perpetrators and the victims." Porizkova continued her lengthy caption by explaining how men are not held to the same standards, as she wondered what that all meant to her.

"Given these social guidelines- I've come to wonder if objectification falls mainly into the realm of youth," she questioned. "When I was a young model exposing my body, it was because someone else approved of it. Someone else decided it was to be celebrated. I didn't know enough to have an understanding of consequences. Hence, objectification." The former supermodel then concluded her post, writing, "Now, when I expose my body, it [is] with my full knowledge and consent. Hence, celebration."
