Shortly before Sean ‘Diddy’ Combs was charged with federal counts of racketeering and sex trafficking, adult entertainer Adria Sheri English had filed an explosive lawsuit against the hip hop magnate.

Diddy, who has pleaded not guilty, has gone by several different names, one of the more recent of which was ‘Love’. But from the tone of English’s complaint, filed on July 2, she wouldn’t agree with the affectionate nickname.

“The things that were forced on me to do … haunt me to this day,” English, who claims in her lawsuit and a criminal complaint Diddy pressed her to have unwanted sex with his party guests, told The Post.

“I anticipate testifying in New York’s Federal Court to help ensure Diddy is imprisoned for life,” she added.

According to the complaint and English’s Miami-based attorney, Ariel Mitchell-Kidd, during 2004 and 2005 she began go-go dancing at the Hamptons parties put on by Diddy.

English, who already had experience working for Larry Flynt’s Hustler Club and sometimes used the stage name Omunique, says in the suit that around the third party things changed.

“She goes back to work at the party, seemingly as a go-go dancer,” Mitchell-Kidd told The Post, based on English’s claims in the suit. “Then Mr. Combs directs her to have sex [with one of the guests]. That was the first time she was required to perform sex acts at a party.”

Sources have told The Post the sexual component would be something of a party-within-the-party. By 2:00 in the morning “the parties would essentially thin out. And then everybody who was still there was kind of with the s–t, if you will. As it got later and later, the people who remained were about the debaucherous activities,” said Mitchell-Kidd.

Describing such alleged activities, which are also listed in the lawsuit, Mitchell-Kidd said, “My client and others engaged in sex acts and [there was] possibly more open drug use. It was more prevalent and nobody’s trying to hide it. That’s when [Adria] would be directed to have sex with this person, sex with that person.”

“There were security guards where the bedrooms were.  Then, as stated in the complaint, English claims she had “forced sexual intercourse” with a guest.

As to why English did it, Mitchell-Kidd recalled her saying, “I didn’t know what to do. I was kind of there by myself.”

Elaborating, Mitchell-Kidd said, “She knew how powerful Mr. Combs was. So, essentially, she just obliged.”

According to a hip hop insider who asked not to be named – and expressed concern that even though he is currently jailed at the Metropolitan Detention Center to wait for his trial, Diddy still wields power – “just obliging” was what people did around Diddy.

“He had [English] under his thumb,” said the source. “That was his thing. There was a fear of being blackballed and having your career ruined if you did not play with him. That was the way he operated to get what he wanted.”

The refreshments being served would have been unlikely to raise English’s inhibitions. “They began to supply her with alcohol,” said Mitchell-Kidd, “which she later discovered to be laced with drugs because of its effect on her.”

The complaint alleges that specific bottles of liquor were spiked with illicit narcotics and female workers at the party were encouraged to drink from those bottles.

No stranger to consuming alcohol – “She worked in a strip club,” said Mitchell-Kidd – English maintained that this seemed to have been something else altogether. “In this instance,” said Mitchell-Kidd, “she didn’t even remember getting home. She didn’t even know if she had gotten paid. The only reason she knew was because the money was in her garter belt.”

The alleged drugging of drinks was an open enough secret that a man who went to Diddy’s mansion in the Hamptons to deliver drugs made it a point to stay away from the flutes of champagne waiters passed around “I would not have any of it,” he said. “They were definitely drugging girls.”

At the bacchanals in Miami where, according to the picture painted by Mitchell-Kidd — who told The Post there were “cameras in every room” — it may have been even more treacherous to consume bubbly beverages.

“I have a client who went to a Diddy’s New Years Eve party [in Miami]. She got there as the party ended and she said, in her words, ‘Everybody was f—ed up.’  She’s, like, ‘I don’t know how much drinking they were doing.’ Now, with this new information I’ve come into possession of, it’s clear that people weren’t just drunk from the alcohol. There was something in the alcohol.”

At a Miami party in 2008, the sexual demands became too much for English. In her lawsuit she claims “Defendant Combs used his power and influence to threaten and intimidate Plaintiff to continue participating in Defendant Combs’ corrupt sex and drug trafficking organization.”

After one encounter where she again claims she was ordered to sleep with party guests, English claims she “got belligerent” with Diddy and his security removed her from the party.

During the party, “she got an attitude [saying] ‘you’re forcing me to do all this sex work. I don’t know that I really want to do this. You’re not really compensating me, and I don’t want to do it anymore.’

“Mr. Combs, she said, gave her this look like, how dare you embarrass me at my party. And she got really afraid. Shortly thereafter, security came and said to her, ‘Hey, we’re going to take you to another location.’ As a punishment, they sent her to a hotel,” according to Mitchell-Kidd, rather than allowing her to stay at the house on Star Island.

Combs had also offered to help English break into the music industry, but carried through on is threat to “blackball” her after she stopped working for him in 2009 and fled to California, her legal team says.

English is not the only one to get booted by Diddy. As reported last week by The Post, former topless dancer Rachel Kennedy put on a sex show for Diddy in Japan and received rough treatment when the rapper decided that he’d had enough.

“[The bodyguard] starts trying to kick us out the door,” Kennedy told The Post, recalling the grueling incident. “We thought he was going to stomp our faces in.”

Kennedy was high on cocaine at the time. English was not on drugs by choice. According to Mitchell-Kidd, during the Miami blowup, “[Adria] said she was drinking the same drinks as the guests and that was the worst experience she had in terms of how she felt the next morning. It was real bad. She was so drugged that she had the audacity to get belligerent with Diddy.”

That was at a point where the services for which she was originally hired, shimmying on a platform to create a good visual for party patrons, were no longer needed.

“As it got later, there was no more go-go dancing,” said Mitchell-Kidd. “It was more about making sure she had sex with whoever the guests were.”

Following the filing of English’s lawsuit, Combs’ lawyer Jonathan Davis told Fox News in a statement: “No matter how many lawsuits are filed, it won’t change the fact that Mr. Combs has never sexually assaulted or sex trafficked anyone.

“We live in a world where anyone can file a lawsuit for any reason and without any proof. Fortunately, a fair and impartial judicial process exists to find the truth and Mr. Combs is confident he will prevail against these and other baseless claims in court,” said Davis.

Diddy’s lawyers have yet to enter a legal response to English’s lawsuit.
