The Wild Rumors About Khloé Kardashian's Biological Father

Khloé Kardashian is the youngest daughter of Kris Jenner and the late Robert Kardashian. She has two older sisters — Kim and Kourtney Kardashian — and a younger brother — Robert Kardashian Jr. — as well as two half siblings, Kendall and Kylie Jenner, from Kris' second marriage. According to OK!, rumors about Khloé's biological father have circulated for many years with conspiracies that she actually isn't Robert Kardashian Sr.'s daughter.

Perhaps it's because Khloé looks very different from her older sisters — she's much taller and has different facial features, including lighter colored eyes — or maybe it's just because people like to create drama, but no matter how you slice it, there are many "Keeping Up With the Kardashians" fans out there who believe that she has a different father than the rest of her siblings. Fan theories that Kris had a secret affair have been abundant, but no one seems to be able to pinpoint who, exactly, may be Khloé's actual dad. That is, if it truly isn't Robert Sr. From O.J. Simpson to Alex Roldan, everyone seems to have their own opinions on Khloé's paternal lineage. 

It seems that there are more fans who believe that Khloé Kardashian's father isn't Robert Kardashian than ones who believe the opposite, which has only caused the rumors to stick around longer. There are a few key players in the game, and some fans strongly feel that Khloé's dad is one of three people: Robert, O.J. Simpson, or Alex Roldan. Over the years, social media users have analyzed side-by-side photos of Khloé with each of these men, drawing all kinds of comparisons based on looks alone. Meanwhile, some of the online conspiracy theorists have taken even deeper dives.

For example, there was a point in time where people truly believed that Khloé looked very similar to Simpson's daughter, Sydney Simpson. Simpson's deceased wife, Nicole Brown Simpson, was really good friends with Kris Jenner and O.J. was good friends with Robert — but did Kris actually have an affair with O.J.? He says it never happened. "I've never been attracted to her and I never suspected she was ever attracted to me, so that was never the case," O.J. said during an interview on the "Full Send" podcast in December 2022. For many, that rumored was squashed then and there. Of course, there are still people who are skeptical. 

Khloé Kardashian found herself at the top of internet discussion in 2016 when someone shared a photo of her along with a photo of Alex Roldan — Kris Jenner's former hairdresser — on Twitter. "Oh and OJ isn't Khloe's dad. It's Alex Roldan, Kris Jenner's hairdresser from the 80s," read the caption of the tweet. Outside of some facial comparisons, fans didn't have much to go on, but some still truly believe that Alex and Kris had an affair and that he is Khloé's true biological father. A less likely name in the mix of who is Khloé's real dad is Lionel Richie. In 2014, a supposed pal of Richie told the In Touch Weekly (via the Daily Mail) that the "American Idol" judge had an affair with Kris. Queue all of the comparisons between Khloé and Sofia Richie! However, that rumor fizzled pretty quickly.

All of the chatter about Khloé's "real" father has certainly been upsetting to her and to the rest of the family. In fact, during an episode of "Keeping Up With the Kardashians" Season 7, Kris actually arranged a paternity test in an effort to put the rumors to bed, according to Entertainment Weekly. In the end, Khloé decided against taking the test. In 2018, however, the Kardashians did 23andMe — which is a DNA test, according to Insider. The results pretty much proved that Khloé had the same parents as Kim and Kourtney.
