We thought it was all settled and so, no doubt, did the Kardashian clan themselves, but despite their insistence that Khloe is the biological daughter of the late legal mind Robert, a new source has come forward to say this isn't actually the case.
Because according to reports today, the reality TV star is actually the real daughter of hairdresser Alex Roldan - and Khloe's mother Kris Jenner allegedly bought his silence!
And according to the source that has come forward with this new information, Kris also included a $30 million clause in a non-disclosure agreement that accompanied the deal with 56-year-old beautician Alex, who has worked with Kris for the last 30 years.

"Alex has been bought up by Kris, so he can’t speak," a source told InTouch.
They added that they "felt terrible for Khloe" who would be "completely betrayed" if she found out and added: "Imagine waking up one day and suddenly realizing your whole life has been a lie."
InTouch also featured a side-by-side photo comparison of Khloe and Alex and pointed out that they have similar eyes, nose and lip shapes.
This is not the first time it has been hinted that Roldan is Khloe's father - last year, radio DJ Gregg "Opie" Hughes gave Khloe and Kris a challenge that would see him pay $250,000 to a charity of their choice if Khloe took a DNA test.
This came after Star magazine in the US first questioned who is Khloe's real father in Janaury last year, which it based on interviews with two of Robert’s ex-wives, Jan Ashley and Ellen Kardashian.
And it was Ashley in particular who was very verbal on the subject and told the magazine: "Khloe is not his kid - he told me that after we got married. He just kind of looked at me and said [it] like it was a matter of fact.
"He said, ‘Well, you know that Khloe’s not really a Kardashian, don’t you?’ And I said…’OK,’ and that was it."
