Emily Ratajkowski alleges Robin Thicke fondled her during filming for Blurred Lines

The model has claimed that Thicke sexually assaulted her during the filming of the controversial music video, with the director backing her claims.

Robin Thicke has been accused of assaulting supermodel Emily Ratajkowski during the making of the video that brought him international fame, the alleged victim writes in a new book.

Ratajkowski said Thicke grabbed her bare breasts while they were filming the Blurred Lines video, the UK’s Sunday Times reported in a forthcoming story.

The song and video, including a web-only version, became a major hit around the world, reported the New York Post.

“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,” writes Ratajkowski, now 30, in the book My Body, set to be released next month.

Ratajkowski was one of three models who appeared in various states of undress in the video, which also starred singer Pharrell Williams and rapper TI.

She initially enjoyed the shoot, according to the report. But then Thicke, apparently drunk, began to behave badly.

“He smiled a goofy grin and stumbled backward, his eyes concealed behind his sunglasses. My head turned to the darkness beyond the set. (The director, Diane Martel’s) voice cracked as she yelled out to me, ‘Are you okay?,’” the book states.

The experience in the Los Angeles studio made the model feel “naked for the first time that day,” the newspaper reported.

“I pushed my chin forward and shrugged, avoiding eye contact, feeling the heat of humiliation pump through my body,” she said. “I didn’t react – not really, not like I should have.”

Martel confirmed the incident, according to the report.

“I remember the moment that he grabbed her breasts,” she said. “One in each hand. He was standing behind her as they were both in profile. I screamed in my very aggressive Brooklyn voice, ‘What the f*ck are you doing, that’s it! The shoot is over!!’”

Martel said that Thicke had been drinking, “sheepishly” apologised and was “contrite” afterwards.

“I don’t think he would have done this had he been sober,” she said.

It’s not the first time the song has caused controversy. The Marvin Gaye estate won a $5 million lawsuit against Thicke and Farrell saying that Blurred Lines was lifted from Gaye’s 1977 hit Got To Give It Up.
