At the start of his testimony, celebrity stylist Deonte Nash saw an airbrushed image of himself that he said, with a smile, was not a fair representation of what he looked like while he was working for Sean Combs and Cassie Ventura.
"I look amazing," Nash told prosecutor Maureen Comey, earning a laugh from the gallery.
Nash said he was around Cassie "all the time" and heard Combs call her names on regular occasions.
"He told her she was an 'outright ho,'" Nash said. He said he heard Combs call Ventura a b**** "quite a bit, that was his favorite."
And "quite a few times," Nash said he heard Combs tell Ventura, "He would beat her a**." He also testified he heard Combs tell her "that he wouldn't put her music out, that he would get her parents fired from their jobs, that he would put out sex tapes."
Federal prosecutors have alleged Combs maintained coercive control over Ventura that caused her to engage in "freak offs" that she did not desire.
Nash told the jury Combs required him to send photos of Cassie in different outfits.
"He would pick which one he liked and that would be the one we went with," Nash said.
He recalled arriving with Cassie at the 2014 Vanity Fair Oscars afterparty.
"She looked bomb. Her hair was down," Nash said, but he told the jury Combs came over and said "I thought I told you she needs to wear her hair up."
Nash said Combs angrily grabbed him by his jacket and lifted him up. "I just started asking people at the party for hair pins," Nash said.
He also recalled one night in 2013 going to a gay club with Ventura, Rita Ora and others. The group returned to Ventura's apartment when he said she "got a call from Puff."
The phone call was on speakerphone and Nash said he heard Combs tell Ventura "that she ought to bring her a** to his house."
He recalled Ventura "started to panic" before Combs called back and told him "we were wild and that he thought he told us not to be going out."
He said Ventura "just packed her stuff and went to his house."
Court is taking its lunch break.
