NEW YORK — The R&B singer Cassie testified Wednesday that her ex-boyfriend Sean “Diddy” Combs kept her in a cycle of abuse and exploitation by threatening to release videos of her engaging in “freak-off” encounters with male sex workers that he orchestrated.

Addressing the court for a second day in Combs’ federal sex trafficking trial in Manhattan, Cassie said she couldn’t reject Combs’ demands and continued participating in the encounters despite being disgusted and humiliated by having sex with strangers. She said she was scared that Combs would ruin her life and make her “look like a slut” by releasing the videos.

“I feared for my career. I feared for my family. It’s just embarrassing. It’s horrible and disgusting. No one should do that to anyone,” said Cassie, whose legal name is Casandra Ventura.

She sued Combs in 2023, accusing him of years of physical and sexual abuse. The suit was settled within hours but dozens of similar legal claims followed from other women, sparking the criminal investigation against him.

Prosecutors showed the jury five still images from the sex videos, recovered from electronic devices that Cassie provided to investigators. Cassie said the images showed her with male sex workers and at various stages of the encounters, which Combs called “freak-offs,” that sometimes lasted days.

Prosecutors have accused Combs of exploiting his status as a powerful music executive to violently force Cassie and other women to take part in sexual encounters. He is charged with five counts, including sex trafficking by force, fraud or coercion.

Combs denies all of the allegations and has pleaded not guilty.

During her first day of testimony, she spent hours recounting details of her decade-long relationship with Combs, including the freak-offs that she said ended in 2017 or 2018. She also said Combs beat her numerous times. The encounters took place in private, unlike Combs’ public parties that attracted A-list celebrities.

Cassie said she met Combs in 2005, when she was 19 and he was 37. Combs signed her to a 10-year contract with his Bad Boy Records label. Within a few years, they started dating, Cassie said.

Her 2006 song “Me & U” went platinum, but when prosecutors asked on Tuesday what happened to her music career, Cassie testified that eventually much of her week went toward engaging in and recovering from the freak-offs, until they “became a job.” She left Combs’ record label in 2019.

She said Combs would routinely threaten to embarrass her by releasing videos of her engaging in sex acts. She said he’d do it when he was angry or to instill fear in her.

Also Wednesday, prosecutors showed Cassie a binder of photos and she identified 13 as male sex workers she recruited at Combs’ behest for encounters in Las Vegas, Miami and Los Angeles.

She testified Tuesday that Combs would pay the men thousands of dollars to have sex with her for 36 or 48 hours, and the longest lasted four days.
