Sean "Diddy" Combs' ex-girlfriend Casandra Ventura has testified that the hip-hop mogul beat her during drug-fueled sex parties known as "freak offs," threatened to release videos of her taking part, and warned he would ruin her career.
"He would grab me up, push me down, hit me in the side of the head, kick me," Ms Ventura, a rhythm and blues singer known as Cassie, told jurors in Manhattan federal court on the third day of Mr Combs' trial on sex trafficking and racketeering charges.
Ms Ventura said Mr Combs was dismissive after she showed him a photo of a gash on her eyebrow that she said he gave her in 2013 by throwing her against a bed frame.
"You. Don't know. When to. Stop," Mr Ventura said Combs told her.
"You have pushed it too far and continue to push. Sad."
Ms Ventura, 38, is the prosecution's star witness.
Mr Combs, 55, has pleaded not guilty to five felony counts of racketeering conspiracy, sex trafficking and transportation to engage in prostitution.
If convicted on all counts, he would face a minimum 15 years in prison and could face life behind bars.
Mr Ventura spent more than a decade with Mr Combs in a relationship she said was once loving but deteriorated.
She told jurors that fighting back against Mr Combs sometimes slowed him down, but usually made the abuse worse.
"It would just make him more violent, make him stronger, make him want to push me harder," Ms Ventura said.
"He said that it would ruin everything that I had worked for, that it would make me look like a slut. That I would be shamed," Ms Ventura added.
"Nobody should do that to anyone."
Jurors viewed a 2013 text where Mr Combs told Ms Ventura he deleted the videos, but Mr Ventura said she still saw them on his devices on several occasions.
Ms Ventura has testified she took part for a decade in "freak offs," often fearful that Mr Combs would become violent if she did not.
Mr Combs is being jailed in Brooklyn when not in court.
Ms Ventura said the video was taken after a "freak off" where Mr Combs gave her a black eye.
Mr Combs has apologised for the video.
Jurors also saw texts after the hotel incident in which Mr Combs asked Ms Ventura to come back because the police were arriving.
Ms Ventura declined, saying she had a black eye and fat lip, and wanted to be rested for a movie premiere the next day.
"You are sick to think it was ok for you to do what you've done," Ms Ventura texted Mr Combs.
"Please stay far away from me."
Mr Combs' lawyers are expected to cross-examine Ms Ventura after she finishes her direct testimony.
The trial could take up to two months.
Mr Combs also faces dozens of civil lawsuits by women and men who accuse him of sexual abuse.
He has denied wrongdoing, and said his relationships were consensual.
Also known during his career as Puff Daddy and P. Diddy, Mr Combs founded Bad Boy Records and is credited with helping turn artists like Mary J. Blige, Faith Evans, Notorious B.I.G. and Usher into stars in the 1990s and 2000s.
