Diddy forced a male adult entertainer to coat his body with baby oil before sexually assaulting him … and the guy says the substance made him incapacitated … at least according to a new lawsuit.

The Bad Boy Records founder is being sued by a John Doe who claims Diddy trapped him in a “vortex of exploitation and fear” … subjecting him to a “relentless pattern of drugging, sexual assaults, death threats, clandestine recording, blackmail and phycological manipulation.”

According to the lawsuit, obtained by TMZ, the guy claims he first met Diddy in 2007 when he was working as an adult entertainer in Las Vegas. He says Diddy would hire him through an agency to dance and strip, but claims their encounters went off the rails sexually once Diddy introduced baby oil.

He claims Diddy led him on for years with empty promises of making him a music star and blackmailed him with videos of their trysts. He says he finally worked up the courage to file a lawsuit after Cassie sued Diddy and the mogul was arrested.

Attorney Lisa Bloom, who is repping the John Doe, tells TMZ … “I am very proud to represent my brave client in this new case. We will not rest until we get justice for him.”

Shaun tells TMZ that he and Shannon will have to try again for another child, adding the thought of becoming a dad gave him a new lease on life … making the loss an indescribable disappointment.

Shaun told us a poor prognosis came from Shannon’s doctor last week, and they found out they lost the baby four days ago. But right now, he says the most important thing is  Shannon’s doing okay, and they’re in this together.

A rep for the United States Secret Service tells TMZ … the incident took place Monday around 4:20 PM, when officers from their Uniformed Division were dispatched to the outer fence on the South Lawn, and the individual was then taken into custody. A protective operations review by the agency will soon be underway.

Law enforcement sources tell TMZ … the suspect is believed to have an unspecified mental issue, and he was taken for an evaluation. He’ll be charged with unlawful entry.
