kim-kardashian-kanye-west-*Things may seem good with Kanye West and Kim Kardashian, but according to insiders, things are not what they seem as West holds a big secret over her head.

What is it?

An insider with knowledge of the situation revealed to In Touch magazine that Kardashian once participated in a tawdry threesome.

“She spent years trying to change people’s perception of her, ever since the sex tape came out [in 2007] and this can undo everything,” said the insider.

Although she’s never been shy about capitalizing off her sex appeal, the insider mentioned that if word got out about Kardashian’s freaky episodes it could damage her brand and business empire.

“She’s also built her brand and an empire” valued at over $40 million,” the insider mentioned. “She’s terrified he will tell the world what he did.”

Despite Kim’s rep denying the threesome, InTouch cites multiple insiders, who detailed how the reality TV star cheated on a longtime boyfriend with West and another famous woman.

“Kanye was obsessed with Kim and wanted to have a three-way with her, and she didn’t hesitate,” one source told the magazine. “Kim and Kanye had already been seeing each other behind her boyfriend’s back, and Kanye brought this other woman into it.”

While that seemed good, the source added that one thing prevented the situation from being a win-win for everybody.

“The other woman ended up getting jealous of Kim because Kanye was more into Kim than he was into her,” the source stated.
