Khloé Kardashian finds herself in the middle of yet another paternity scandal, as a new report claims that hairdresser Alex Roldan could be her biological father.

According to Celeb Dirty Laundry, Rob Kardashian, who reportedly wants to sue his notorious family for mentioning him as well as his personal issues (alleged drug abuse, depression, weight gain, etc.) on "Keeping Up with the Kardashians," plans to expose that Roldan is his sister's real father -- over hatred and for money.

As a result, matriarch Kris Jenner feels "nervous," because the last thing she wants is "for the world to know that Khloé Kardashian isn't a Kardashian."

The 30-year-old has been dealing with incessant allegations that the late Robert Kardashian is not her father for quite a while. For instance, O.J. Simpson's manager Norman Pardo came forward in 2013, claiming that the jailed former NFL star could be her dad.

"It's all going to come out sooner or later. Khloe could be O.J.'s kid," Pardo told In Touch. "Whenever I bring it up, he giggles."

Simpson, who infamously was acquitted of the murders of ex-wife Nicole Brown and Ron Goldman, was supposedly very close to Robert. Also, he has never denied the rumor that he and Jenner had an affair, wherein the latter became pregnant with Khloé.

"They all took their vacations together. There was a lot of partying going on back then," Pardo added. "Kris cheated on Robert -- she was known for having a good time."

In addition, another source revealed to In Touch last year that Lionel Richie is Khloé's potential father.

Jenner allegedly had a fling with Richie back in the "wild 1980s," while still married to Robert: "They had a sexual affair -- he bragged about it. He said he was on the outs with his wife at the time," the source said. "Everyone was sleeping around with everyone else back then, and Kris was hot in those days."

Jacky Jasper, founder of blog Diary of a Hollywood Street King, also admitted to the publication, "Kris had an affair with Lionel -- and I believe he is Khloé's dad."
