Robin Thicke allegedly crossed a line on the set of his 2013 music video, according to Emily Ratajkowski.

In her next essay collection, My Body, the model-actress writes about her experience making the 2013 music video with singer Robin Thicke. Ratajkowski, now 30, claims that Thicke touched her naked breasts on the set of the uncensored video, according to an extract published by The Sunday Times, which appears to have acquired an advance copy.

Thicke, according to the 30-year-old, “returned to the set a little drunk to shoot just with me”

Ratajkowski writes that, “Suddenly, Out of nowhere, I felt the coolness and foreignness of a stranger’s hands cupping my bare breasts from behind. I instinctively moved away, looking back at Robin Thicke.”

The text continues, “He smiled a goofy grin and stumbled backward, his eyes concealed behind his sunglasses. My head turned to the darkness beyond the set. [Director Diane Martel’s] voice cracked as she yelled out to me, ‘Are you okay?'”

It goes on to say that Ratajkowski felt “naked for the first time that day” after the event and that she was “desperate to minimize” the situation. “I pushed my chin forward and shrugged, avoiding eye contact, feeling the heat of humiliation pump through my body. I didn’t react—not really, not like I should have,” she writes.

“With that one gesture, Robin Thicke had reminded everyone on set that we women weren’t actually in charge. I didn’t have any real power as the naked girl dancing around in his music video. I was nothing more than the hired mannequin,” she continues.

The alleged incident was apparently observed by director Martel, according to The Sunday Times. “I remember the moment that he grabbed her breasts. One in each hand,” she said. “He was standing behind her as they were both in profile.”

Martel said that she yelled, “‘What the f–k are you doing, that’s it!! The shoot is over!!'” In addition, she told the newspaper Thicke “sheepishly apologized. As if he knew it was wrong without understanding how it might have felt for Emily.”

The song and video were both heavily criticized at the time for their blatantly misogynistic, sexist tone and objectification of women, with Vice describing the video as “a masterpiece of idiocy,” with the level of stupidity and arrogance required in order for a video this banal, offensive, and unimaginative being “almost impressive.”

In a 2015 interview with The New York Times, Thicke said, “Pharrell and I have never and would never write a song with any negative connotation like that. I think the song on its own—I don’t think that would have existed. Once the video came out, that changed the conversation.”

Thicke has not responded to The Sunday Times’ allegation, although he previously told People that he was taking pills and alcohol while going through a divorce with Paula Patton at the time the controversial track became a hit.

“You don’t realize you’re not in control. Fame and a lot of those things—they got to me. I was in a bad place. I’m happy to have closed that chapter,” he said.

In 2013, “Blurred Lines” was a No. 1 hit. Thicke, rapper T.I., and Pharrell Williams appear in the music video dancing with models, including Ratajkowski, who is topless in the unrated version.

Thicke defended the video in 2013, telling the BBC that his critics don’t “get” the song.

The estate of Marvin Gaye won a $5 million lawsuit against Thicke and Farrell, alleging that “Blurred Lines” was ripped off from Gaye’s 1977 hit “Got To Give It Up.”

The book, which will be published by Macmillan on November 9th, is described as “a deeply honest investigation of what it means to be a woman and a commodity… a profoundly personal exploration of feminism, sexuality, and power, of men’s treatment of women and women’s rationalizations for accepting that treatment. These essays chronicle moments from Ratajkowski’s life while investigating the culture’s fetishization of girls and female beauty, its obsession with and contempt for women’s sexuality, the perverse dynamics of the fashion and film industries, and the grey area between consent and abuse.”
