Rumors that Khloe Kardashian is not the biological daughter of Robert Kardashian have been circulating for years.
Everyone from A-list celebrities to Hollywood hairdresser Alex Roldan have been reported to be Khloe's real dad, with anonymous family "insiders" coming out of the wood work to confirm that Kris Jenner slept around during her first marriage.
Recently, rumors that O.J. Simpson is Khloe's real father resurfaced after a woman claiming to be O.J.'s transgender prison lover claimed that the reviled running back confessed his paternity during their affair.
Needless to say, the debate over the identity of Khloe's dad has frequently veered into absurd territory, and it looks more and more as though there will never be a conclusive answer.
Even so, the stunning resemblance between Khloe and Lionel Richie's daughter Sophia has the rumor mill churning once more:
The Kardashians and the Richies have been close for years (Kylie Jenner was recently rumored to be dating Lionel's son, Miles), so naturally there's no shortage of reports that Kris and Lionel once got it on.
Sources confirmed to Radar Online recently that Kris and Lionel carried on a "sexual affair" in the late 70s and early 80s, adding that Richie frequently "bragged about" his trysts with Kris.
"She was a big flirt and played around," said Daniel DiCriscio, a longtime friend of Kris'. "I've seen Kris do things that would blow people away. I know Lionel was a huge player back then too."
The Richie and Kardashian-Jenner clans are so close that Lionel is already said to be something of a father figure to Khloe. And she's reportedly considered the fact that she may share some DNA in common with the R&B icon.
"She's not going to go there and ask if he's her dad, but she does think he's a great father," says the source. "If Lionel is her dad she'd probably be okay with it."
Frankly, we think Khloe should attempt to croon an 80s-style romantic ballad to find out for sure. Way more fun than a paternity test.
