Music mogul Sean “Diddy” Combs, who was arrested this week on suspicion of human trafficking, is also the subject of a memoir in which he alleges he had sex with a famous male teenage pop star, hosted sex parties with an A-list actor and his wife, and abused his ex-girlfriend Kim Porter.

The memoir, a slim 60-page book based on Kim’s diary entries, describes orgies that Diddy, now 54, organized and participated in, his sexual relationships with male and female musicians and alleges that he taped himself having sex with “young boys” whose careers he managed.

Kim, 47 when she died, has three children with the mogul: son Christian (26) and twin daughters D’Lila and Jessie (17).

The memoir, Kim’s Lost Words, which was published a few days before Diddy’s arrest, was written by publisher Chris Todd under the pseudonym Jamal T Millwood.

Kim’s diary entries were on a flash drive given to him by a well-known friend, Chris told the Daily Mail.

“I know the source of the fame pretty well. I know how close they were to Kim and Diddy, and all the people in the hip-hop community.”

Chris used a pseudonym, he said, because he was afraid for his life, but now that Diddy is in prison, he feels safer talking about the book.

ORGIES

According to Kim’s book, Diddy organized orgies that resembled extravagant parties.

“Not only did we have threesomes, but we also swapped partners. Our sex life was crazy, but I did things with Sean that I could never have done with a straight man,” she wrote.

She recounts the night she caught Diddy coming out of her bedroom with “a chart-topping rapper” – and the woman’s husband.

“I was glad I wasn’t asked to be in that room,” she wrote, because she “didn’t really like the rapper that much.”

ALLEGATIONS OF ABUSE

Diddy has been accused of assault on multiple occasions. Earlier this year, a video surfaced of him attacking his ex-girlfriend Cassie Ventura (now 38) in a Los Angeles hotel.

Kim describes Diddy in her memoir as a “terrifying monster” who also abused her during their 13-year relationship.

The memoir alleges he first hit her after she refused to use a strap-on sex toy on him.

“Then Sean hit me. It was the first time, but he hit me hard. Before I could form words, he started begging, ‘I’m sorry… I’m sorry.’

“I held my cheek where he hit me, turned around and ran. That should have been it. But I guess I’m a punishment masochist.”

SEX TAPE

Kim wrote that Diddy allegedly recorded his “marathon” sex sessions with teenage girls and male sex workers.

“Some of the tapes had things I never expected; the gay parties are one thing, but the young boys, like (two hip-hop stars managed by Diddy) and (the then 18-year-old pop star)?! I never would have known.”

She reportedly made copies of the tapes to protect herself, as part of her plan to leave Diddy.

Chris told the Daily Mail that he had been given access to the sex tapes.

“I’m sure (Diddy’s sex tape with the teen pop star) was sold to Hollywood studios by other parties,” he said.

Meanwhile, Diddy, who has pleaded not guilty to the charges, has been denied bail and is being held at the Metropolitan Detention Center in New York City, which was also home to R. Kelly and the late pedophile Jeffrey Epstein.

No date has been set for Diddy’s trial. His lawyers say they will appeal the decision not to grant him bail.
