Pop singer Casandra Ventura testified on Wednesday in Manhattan federal court that she passed out in a Hamptons hotel room in 2013 after taking club drug GHB and woke up in the shower with rap mogul Sean "Diddy" Combs and a male escort standing over her.

Ventura, 38, who met Combs when she was 19 years old and he was 37, spent two days on the witness stand detailing a jetset lifestyle with the rap star filled with parties, dayslong orgies and drug use. Behind the glamour and the music, the singer known as Cassie told the jury that she endured a cycle of physically and emotionally scarring violence, followed by apologies and more abuse before she finally  ended the relationship in 2019.

The Bad Boy Records founder, who grew his music business into a multinational billion-dollar empire, including vodka and tequila brands, the Sean John clothing line and entertainment programming,  is on trial for racketeering, sex trafficking and transporting men across state lines for prostitution.

Combs has pleaded not guilty and his defense attorney says the case is about a series of toxic relationships by women who were jealous of Combs' infidelities and sought to cash in after their breakups. His lawyers say the sexual encounters were consensual. 

Prosecutors  said that Combs used his bodyguards, personal assistants and company executives to enable his sex parties, dubbed freak-offs or king parties, then coerced his girlfriends to participate, blackmailing them to continue by threatening to release videos taken during the sexual encounters.

On Monday, the jury, consisting of eight men and four women, viewed a hotel surveillance video that purportedly showed Combs pulling Ventura to the ground by the back of her neck and then kicking her repeatedly before trying to drag her back to his room.

She testified on Wednesday that violence was frequent.

In this instance, Ventura told jurors, she tried to leave a  sex party after he had punched her in the eye. Ventura said she had a movie premiere that she was supposed to appear at and was upset that she would have a black eye.

"You are so sick to think it’s OK to do what you’ve done," she texted him, she said. "Please stay away from me."

She did not call the police, though, because she said that she loved him, despite being encouraged to get help by her friends, she told jurors. A friend called the police after the incident, but Ventura did not press charges, she said.

"In that moment, I didn’t want to hurt him that way. I wasn’t ready," she said.

Fighting back against Combs only made him angrier, she testified.

"I did that more on the earlier side of the relationship," she said about resisting his alleged fits of anger. "I learned that would make it worse for myself. Make him stronger, more violent."

She told jurors she became an expert at styling her hair over black eyes or putting on enough makeup to hide the bruises from Combs’ beatings.

Once, in August 2013, when she was packing to go to Drake’s OVO music festival in Canada, Combs came to her apartment in a rage, she said. Two of her friends jumped on his back to keep him off her, but he was too strong and shoved her into her bed frame, causing a large gash over her left eye, she said. Instead of going to the hospital, he took her to a Beverly Hills plastic surgeon to get patched up, she testified.

Combs became furious again when she texted him a photo of her injured eyebrow, she told jurors.

"At the very least, I just wanted him to be sorry about it," she testified. Instead, she said, she ended up having to appease him during a trip to the Hamptons.

With the scar still unhealed, he proposed another sex party in a Hamptons hotel room, she said.

Ventura said that she began taking drugs to "dissociate" during the sex sessions, during which she would have sex with male prostitutes and Combs.

She said that in the hotel, she took GHB, a club drug that causes euphoria, and then blacked out.

"I woke up nude in the shower and Sean and Dave were freaking out," she said, referring to the name of the alleged male prostitute.

"I didn’t see myself, but it wasn’t pretty," she testified. 

Ventura testified that the fights got worse and that to control her, Combs threatened to release copies of the videos of their sex life to the public.

"I just felt trapped," she said. "I mean, how do you get out of this situation?"

Ventura said that she moved on, got married and had two children, but the threats from Combs continued.

She tried to carry on with her career, but she continued to feel despair from what she called post-traumatic stress disorder caused by her time with Combs.

"I was spinning out," she testified. "I just kept having these horrible flashbacks."

Ventura said she sought therapy in February 2023 for drug and psychological abuse. She wrote a book about her time with Combs and sent it to him, offering him the rights for $30 million.

In November of that year, she testified, she sued him for sex trafficking and rape. The case settled after a day for $20 million. At the time, Combs' attorney said the settlement was not an admission of wrongdoing.

Ventura returns to the witness stand Thursday morning for cross-examination.
