“She’s like, ‘Oh, he’s having a Diddy party,'” he recalled. “These Diddy parties are f–king crazy. They’re the best parties, like, people wanted to go to them.”

Expecting a “normal party,” Wittek said he showed up to the bash in a polo shirt, whereas his acquaintance and another friend wore lingerie where “their nipples are showing through.”

“And I’m like, ‘You guys are going like that?’” Wittek recalled. “They’re like, ‘You don’t understand about these parties.’ And I did not understand ’cause I saw live  happen that night.”

“That’s the first time I saw that happen ever in my life. And did I partake? No, but I got f–king drunk there,” he continued. “It’s just crazy. I was literally there. I lived through it.”

The events of the alleged “Freak Off” are the focus of the federal investigation into Combs, who was arrested in New York on September 16 on charges of conspiracy to defraud, trafficking in ….

“During Freak Offs, Combs distributed a variety of controlled substances to victims, in part to keep the victims obedient and compliant,” prosecutors said in the document. “After Freak Offs, Combs and the victims typically received IV fluids to recover from the physical exertion and drug use.”

Combs, 54, has maintained his innocence as he awaits trial, pleading not guilty to charges on Sept. 17.

“Please reserve your judgment until you have all the facts,” his attorney Marc Agnifilo told reporters at the courthouse Sept. 17. “He looks forward to clearing his name in court.”
