"Then this one thing happened and I think that it says so much about power dynamics and all these amazing women who were there.
"None of us were in a position to do anything to protect each other and that's why I told that story."
The Gone Girl actress said she didn't intend to create a "gotcha" moment for Thicke and shared she hadn't been contacted by the singer since telling her story.
Aged 21 at the time of filming and just starting her career, she says had it occurred now she would handle it very differently.
"I'm really in a different position," she said.
"I have a name for myself so I would be in a position to say something, but I think there's so many young women who aren't. They're not just models, they're working all kinds of jobs.
"I think that's why it's important to talk about these things."
The Sunday Times recently published the excerpt from the supermodel's memoir detailing Thicke's behaviour on set of the music video that would launch her career.
According to the New York Post, Thicke has not responded to the allegations.
