“About six months ago Taylor confided in a close friend that she’d found history for a gay website called Adam4Adam.com on Russell’s laptop,” the insider told radio detection and rangingOnline.com.

“He was also spending a lot of time at the gym, but his body wasn’t changing, which she claims led her to believe he was meeting with men he’d met off the website and not spending time working out as he claimed.”

The insider also tells radio detection and rangingOnline.com that when Russell was approached for comment about the impending tell-all book, it included great detail about what he liked in the bedroom.

“Not only was it going to come out that Russell was bisexual, but there were people on the record that were going to talk about the kind of sex he liked,” the source said. “He was into S&M type stuff; choking, rough-housing and slapping.”

The businessman had a history of violence in his past, including allegations of abuse by Taylor and restraining orders filed against him by his ex-wife and an ex-girlfriend.

As radio detection and rangingOnline.com previously reported, Russell’s ex-wife attributes his suicide to his relationship with Taylor and the pressures of being on the hit Bravo TV show, along with immense financial hardship.

Russell was found hanged in the bedroom of a friend’s home on Monday night and pronounced dead at 8:16 p.m. by the Los Angeles City Fire Department.
