New documentary about Sean "Diddy" Combs claims his mother threw wild parties in his childhood home.

"Diddy: The Making of a Bad Boy" premieres on the Peacock on January 14, and a childhood friend claimed in the documentary that Janice Combs' partying may have been "desensitized" to the music mogul.

Diddy's childhood friend and producer Tim “Dawg” Patterson said Diddy's mother threw parties at the house where they were exposed to adult bedroom sex.

According to Rolling StonePatterson claims in a new documentary that Diddy was exposed to adult sex at his mother's parties.

Diddy is currently in a New York jail awaiting trial for sex trafficking. The music mogul has been accused of human trafficking for his infamous sex parties known as "scams", and Paterson said it "goes back to childhood".

"I was always asked why," Patterson said. "I don't know the answer to why, but I really believe it all goes back to childhood."

Patterson added that seeing what happened in Diddy's childhood home may have shaped the Bad Boy founder.

In the movie "Diddy: The Making of a Bad Boy," Patterson claimed that he and Diddy were exposed to people having sex during parties hosted by the music mogul's mother. The producer also said that they were exposed to drugs and alcohol.

“On the weekends, (Combs) would party at the house, and we did that a lot,” he recalled. “He was around all kinds of alcohol; he was around the smoke. Drug addicts around, lesbians around, homosexuals, he was around pimps, pushers. That was who was in our house. The people who attended the parties were from Harlem, from the streets."

Paterson added that partygoers will go to bedrooms for sex.

"It wouldn't hurt if you accidentally walked into one of the bedrooms and put a couple of bare bums in there," he said. "Did it desensitize us? I'm sure it did. Were we aware of it? No, it was just a Saturday night."

During the interview with VIBE magazine back in 1999, Diddy shared details of his childhood and revealed that he lost his virginity when he was just 12 years old.

The "Act Bad" singer said he started masturbating at 11 while watching softcore porn on Midnight Blue.

"I watched it and was blown away when I was 11," he said.

"I acted like porn stars act," he added about losing his virginity. "I shelled it like. I spanked girls! I didn't do it on my own, she wanted me to spank it like. I flipped her over because I saw it on film and then she told me to do it again, so you know."

This was also revealed by the VIBE article Diddyex-girlfriend, actress Jennifer Lopezshe was lying on the couch in the singer's tour bus while "Real Sex" played on the television during the interview. The HBO reality show explored sexual trends during the 1990s.

"His girlfriend, actress/singer Jennifer Lopez, clearly exhausted, is lying on the sofa, the top of her head peeking out from under the brown blanket she's cocooned in. HBO's Real Sex is on the channel," the article reads. "Six naked white guys and a confused sister rolling in a big pile of mud flash on the screen."

In the trailer for "Diddy: The Making of a Bad Boy," an associate of Diddy's claimed that he likes to use red lights for his sex parties.

"I've been with Shawn for a long time," remarked one associate in the trailer. "And I caught a lot of moments. Whenever the studio or any room is red, he's making love and having sex. Some of the girls that were in the room must have been underage."

"Diddy: The Making of a Bad Boy" will debut Jan. 14 on the Peacock.
