AceShowbiz - More people have spoken up about Sean "P. Diddy" Combs' dark side. Amid federal investigation for alleged sex trafficking and multiple lawsuits accusing him of sexual abuse and drugging, his close friends and former associates have spoken out against him.

On Tuesday, May 28, Rolling Stone published its six-month investigation into the horrified allegations leveled against the Bad Boy Records founder. According to the publication, "out of 300-plus people contacted for this investigation, more than 50 were willing to speak about their experiences. Those who did speak about Combs describe a complicated man with opposing personas."

While outwardly Diddy would be seen as "unapologetically driven, generous, and jovial, even silly at times," those "who got close enough to him discovered something darker behind the facade: a menacing figure who desperately wants to be accepted and admired, who uses public declarations of devotion, splashy donations, and boasts that he is 'Brother Love' to hide an undercurrent of alleged abuse and violence."

Some instances cited by the outlet include his alleged beating of a label executive bloody after he became romantically involved with Diddy's ex-partner Kim Porter, and allegedly trying to solicit sex from a woman on his payroll.

The magazine also spoke with Diddy's classmates at Howard University, who detailed his alleged abuse on his then-girlfriend with a belt. "Puff is out here acting crazy. He's beating her," one classmate recalled what fellow students said at the time.

"He screamed and hollered and acted a stone fool until she came downstairs," another Howard student who witnessed the alleged attack told the outlet. She said Diddy used what appeared to be a belt to strike the young woman "all over the place."

The witness said Diddy appeared "super angry" and was "screaming at the top of his lungs." The second witness added that the rapper "whupped her butt - like really whupped her butt," adding that they thought the woman was clearly terrorized. "She was trying to defend herself a little bit. She was crying. And we were telling him, 'Get off of her.' We were screaming for her," the witness claimed, which was confirmed by a third witness.

Photographer Monqiue Bunn, meanwhile, suggested Notorious B.I.G.'s death could have been more sinister than initially thought. "[Biggie] was absolutely about to leave Puff," Monqiue said of the late rapper, who was signed to Bad Boy Records. "I know for a fact [because] he told me that." Another source added, "Everybody wanted to leave Puffy. Everybody leaves him."

In response to the article, Diddy's lawyer Jonathan Davis said in a statement to the outlet, "Mr. Combs cannot comment on settled litigation, will not comment on pending litigation, and cannot address every allegation picked up by the press from any source, no matter how unreliable."

The lawyer added, "We are aware that the proper authorities are conducting a thorough investigation and therefore have confidence any important issues will be addressed in the proper forum, where the rules distinguish facts from fiction."
