Exclusive Diddy's alleged sick list of requirements for a 'freak off' sex party — as a party planner, he revealed he kept scales in the car to make sure all the women weighed under 140 pounds.

Diddy was very particular about the women attending his “Freak Off” sex parties — one party planner told The Post that he kept a scale in his car to make sure no female guest weighed more than 140 pounds.

“We will do a ver-in if necessary,” said the organizer, who worked with DD in 2004 and 2005 and asked to remain anonymous. “The girls had to be young and hot, so I always had a scale with me in case I needed to make sure. The number was 140 pounds, but if a girl was really tall, there was some discretion involved.”

In the DD's decree, there were some other requirements. “No flab, no cellulite. No excessive piercings or tattoos. No short hair. And the girls have to be young and hot.”

Even the dress code was strict: “No pants. no jeans No flat shoes. Every girl should wear a party dress, preferably very short, enough to cover her butt cheeks, but no more than mid-thigh. Showing cleavage. And they each had to wear stilettos. That one, was no exception: high stilettos.

One thing the organizers never asked, the source said, was the age of the girls.

“It's not asked, don't tell. At the time, I was really young myself and I honestly thought we were not asking their age because of the liquor laws,” the source said.

“I've never been around for freak-offs and had no idea these girls were expected to have sex with people.”

A second source — a petite dancer who performed at Combs' 2005 VMA afterparty — told The Post that she was paid $250 to dance at the mainstream event, but was paid an additional $1,000 when she later visited Diddy's house for more dances.

“It felt shady,” she said, adding that she was only 20 at the time, “so I didn't go. But other girls did, and then wouldn't really talk about what happened there.”

The post saw more than two dozen videos of the raunchy sex party, which appeared to be footage from Diddy's Freak Off that was linked to mainstream events like the MTV Video Music Awards or the Super Bowl. In the videos, women matching the description are seen having sex with men as combs are apparently seen in the background.

In one video, Diddy was seen getting in on the action himself, holding the camera from his point of view as he was seen having sex with a woman.

The alleged conduct is consistent with similar allegations made earlier this month. In one lawsuit, a woman alleged that Diddy and a female celebrity raped her when she was just 13 years old while following the 2000 VMAs at Radio City Music Hall in New York.

In addition, Texas-based lawyer Tony Buzbee revealed a new wave of accusers — including a 9-year-old at the time — who planned to sue the music mogul for alleged sexual abuse and exploitation.

Sean “DD” Combs has repeatedly denied wrongdoing.

His attorneys denied the latest allegations in a statement. “In court, the truth will prevail: Mr. Combs never sexually assaulted anyone – adult or minor, male or female.”

Federal officials raided two of Diddy's homes in March and seized mountains of sexual paraphernalia, including hundreds of sex videos and 1,000 bottles of baby oil and lube. In a statement, the US Attorney's Office alleged that the sex parties were not always consensual.

His alleged sexual abuse of the women included forcing them to engage in frequent, day-long sexual acts with male prostitutes, some of whom were “transported across state lines,” according to the charges against him.

“These 'freak offs' were elaborate sexual performances that he orchestrated, directed and often electronically recorded,” the document alleges.

“To ensure participation in the freak-off, Combs used violence and intimidation and used his power over the victims — power he gained by obtaining and distributing drugs to them, extorting his financial support from them and threatening to cut it off and their careers. Regulates the authority's complaint.

It's unclear whether the videos the Post viewed were part of the feds' case

DD has been charged with conspiracy, sex trafficking and transportation for engaging in prostitution. In addition to the charges, he faces numerous civil lawsuits from his alleged victims.

He pleaded not guilty and said the “freak offs” were consensual.

His attorneys did not return The Post's calls for comment.
