Blac Chyna Has an Explosive Secret About Khloé Kardashian and Scott Disick’s Relationship (EXCLUSIVE)

As Life & Style exclusively reported, Blac Chyna is planning to write a tell-all about the Kardashian Klan after her breakup with Rob — and she’s got some interesting dirt on Khloé Kardashian and Scott Disick’s bizarre relationship.

After the 32-year-old fought to keep Chyna from trademarking the Kardashian name, the mother-of-two isn’t planning on holding back when it comes to Khloé’s chapter in her book.

Scott, who’s Kourtney Kardashian’s baby daddy, once bragged about having sex with Khloé in a Hamptons, NY, shower, and a source tells Life & Style that Chyna knows what really went down between the duo, including whether there was other inappropriate behavior between them.

She also has the scoop on Kourtney’s fling with 23-year-old Justin Bieber. “Kourt tried to cover her tracks at first. But Chyna heard about how angry her younger sisters were about it,” the source shares.

Given that Chyna and Rob had a relatively amicable split, the insider says that she plans to go easy on her former fiancé, but will open up about his depression and unhealthy habits like binge eating and partying.

“She’ll expose how the rest of the family turned their backs on him,” the source says. “She feels she’s got nothing to lose. It’s a no-brainer. Chyna has always had a rocky relationship with the Kardashians and sees the book as payback. She knows it could make her millions and ensure she never has to work another day in her life.”

Of course momager Kris Jenner is “petrified that she’s going to reveal the truth about what goes on behind closed doors,” but Chyna “knows everything about the family from her pillow talk with Rob.”
