Last week, Mr. Combs stepped aside as chairman of Revolt, his cable TV network. Diageo, the alcoholic beverage giant that Mr. Combs is suing over allegations that it treated unequally the brands he has promoted because he is Black — which the company denies — told a New York judge that its DeLeón tequila brand could not continue to feature Mr. Combs in promotional material. The company said in a court filing that his “now-toxic image” made it “impossible for him to continue to be the ‘face’ of anything.”

In the most recent suit, the unidentified woman says she was with friends at a lounge in the Detroit area when she met Harve Pierre, Bad Boy’s former president, who is also named as a defendant in the case and is accused of taking part in raping the woman. The woman, according to the court papers, said Mr. Pierre told her that Mr. Combs “would love to meet” her and then, in a bathroom at the lounge, Mr. Pierre “demanded” oral sex, before asking her to accompany him on a private flight to New York City.

While at the recording studio, according to the suit, the woman met Mr. Combs and took a photo sitting on his lap, which was included in the complaint with her face obscured. “Ms. Doe became more and more inebriated,” the complaint reads, “eventually to the point that she could not possibly have consented to having sex with anyone, much less someone twice her age.”

Eventually, the lawsuit says, Mr. Combs directed her into the bathroom, where he raped her, and then sat in a chair outside the bathroom watching as an unnamed man raped her. The suit says Mr. Pierre assaulted her last.

Mr. Pierre could not be reached for comment, but in a statement to TMZ on Dec. 8, he called the lawsuit a “tale of fiction,” and added, “I have never participated in, witnessed, nor heard of anything like this, ever. These disgusting allegations are false and a desperate attempt for financial gain.”

Mr. Pierre was named in an earlier case, filed last month, which accused him of grooming and sexually assaulting an assistant at Bad Boy. Mr. Pierre’s statement to TMZ said that he would “vigorously protect” his reputation and defend his name.
