Music/film mogul Russell Simmons is being accused by a former model of forcing her to engage in sex as filmmaker Brett Ratner watched and did nothing, according to a report.

Keri Claussen Khalighi said she was 17 years old when the incident happened in 1991 at Simmons’s New York apartment. The story was first reported Sunday by the Los Angeles Times.

She fought off the attempt at sexual intercourse, but Simmons coerced her into oral sex. “I guess I just acquiesced,” she said. When finished, she went to take a shower. Simmons joined her in the shower and briefly penetrated her before she managed to fend him off.

Khalighi claimed she accompanied Simmons and Ratner to the apartment to ostensibly watch a music video they had co-produced. When they arrived, Simmons aggressively removed her clothes. She claims she asked Ratner for help, but he did not respond. “I’ll never forget the look on his face,” said Khalighi. “In that moment, the realization fell on me that they were in it together.”

“I know Keri Claussen Khalighi and remember the weekend in 1991 that she has referenced,” Simmons said today (read the full statement below). “Everything that happened between us 26 years ago was completely consensual and with Keri’s full participation. Let me be crystal clear and very direct: Abusing women in any way shape or form violates the very core of my being. I have always spoken out regarding my life experiences, women’s issues and the need to bring a faster and more decisive shift in the collective consciousness that will help bring about true women’s equality.”

The Times story quoted Ratner’s attorney, Marty Singer, as saying his client has “no recollection” of any requests for help by Khalighi. Ratner has been accused of sexual misconduct by several women, among them actresses Natasha Henstridge and Olivia Munn.

Ratner and Simmons were investigated by Beverly Hills police for an alleged sexual battery in 2001, but no charges were brought.
