Cassie Ventura is set to testify against her ex-boyfriend Sean “Diddy” Combs in his upcoming sex trafficking trial next month.

The “Me & U” hitmaker, 38, will be using her name in court rather than testifying anonymously, a motion filed Friday revealed.

Prosecutors mentioned that “Victim-1” was set to testify in the trial of the disgraced music mogul. The mogul has faced allegations of drugging and assaulting individuals of both genders throughout many years. Despite the accusations, the mogul has maintained his innocence and entered a not guilty plea for his criminal charges.

In January, Rolling Stone identified “Victim-1” as Ventura.

Combs, 55, also faces charges of racketeering conspiracy, sex trafficking and transportation to engage in prostitution. His trial is set to begin May 5.

“She is prepared to testify under her own name,” the filing states, per People. “Victim-2, Victim-3, and Victim-4 have asked that their identities not be revealed to the press or the public.”

Additionally, prosecutors requested that the anonymous victims “be referred to at trial using only pseudonyms.”

“This case has already received an exceptional amount of media coverage, which will presumably only increase as trial proceeds,” the filing stated.

“Permitting these measures will prevent unnecessary public disclosure of the victims’ identities, and the harassment from the media and others, undue embarrassment, and other adverse consequences that would almost certainly follow if these women were forced to reveal their true names publicly at trial.”

The Post has reached out to Combs’ reps for comment.

Southern District of New York feds revealed Monday that they plan to include testimony about “sexual abuse of other victims” at Combs’ trial on charges of forcing lovers into drug-fueled, days-long sex marathons dubbed “Freak-Offs,” and running Bad Boy Records as a criminal enterprise.

Notably, the so-called “Freak Offs” — drug-fueled, dayslong performances of sexual depravity that an observing Combs would masturbate to, according to the indictment — were detailed in Ventura’s November 2023 lawsuit describing the decade-long nightmare she allegedly endured.

Ventura — an R&B singer once signed to Combs’ label Bad Boy Records — said the first “Freak Off” happened just months into their dating, when she was around 22 and he was 40.

After she filed the lawsuit, Combs threw a last-ditch attempt to keep the matter hushed by settling the suit a day after she filed.

Still, allegations of the “Freak Offs” now serve as a main basis for the bombshell federal sex trafficking and racketeering indictment unsealed on Tuesday.

Among the myriad of allegations, Ventura’s suit claims that Combs frequently had exploitative sex shows take place at various hotels.

She also alleges that the rapper forked out large sums of cash for escorts to take part in the sexual performances, during which he would sometimes physically abuse her in front of them, the suit claims.

Combs made Ventura the lead producer in his sicko sessions, ordering her to find male sex workers online, the suit alleges.

When Ventura tried to protest participating in a session, she would be “brutally” beaten, the suit states.

Indeed, months after the suit was settled, harrowing video footage from 2016 emerged that showed Combs beating Ventura in a hotel hallway.

The “Long Way 2 Go” hitmaker’s lawsuit inspired a number of other women with similar claims to come forward.
