The internet has a weird obsession with things that aren't actually true. If you’ve spent more than five minutes on TikTok or scrolled through a tabloid comment section, you’ve seen the theory. People are convinced that Khloé Kardashian is actually O.J. Simpson's daughter.
It’s been a thing for decades.
Honestly, the rumor is like a zombie. Just when you think it’s finally dead, a new episode of The Kardashians drops or a vintage photo resurfaces, and the whole thing starts up again. It doesn't matter how many times the people involved say "no"—the public loves a good conspiracy. But if we’re looking at the actual facts, the "OJ Simpson Khloe Kardashian daughter" story is basically built on vibes rather than evidence.
Why the Rumor Won't Quit
The whole mess started because Khloé doesn't look like Kourtney or Kim. While her sisters have that classic Armenian look from their father, Robert Kardashian Sr., Khloé was taller, had lighter hair, and different facial features growing up. People looked at her, looked at O.J. (who was a very close family friend), and decided they’d solved a mystery.
It’s kinda mean when you think about it. Imagine the world constantly telling you your dad isn't your dad.
Kris Jenner hasn't helped matters much in the past. In her 2011 memoir, she admitted to having an affair during her marriage to Robert. She didn't say it was with O.J.—in fact, she’s explicitly said it wasn't him—but that one admission gave the conspiracy theorists all the fuel they needed. If she cheated once, they figured, why not with the guy Robert was defending in the "Trial of the Century"?

The "Uncle O.J." Connection
The Kardashians and the Simpsons were genuinely tight. Robert Kardashian was one of O.J.’s closest friends long before the 1994 trial. Kris was best friends with Nicole Brown Simpson. The kids grew up together. Khloé literally grew up calling him "Uncle O.J."
That level of proximity makes for a great soap opera plot, but it’s not DNA proof.
What O.J. Simpson Actually Said
Before he passed away in 2024, O.J. Simpson addressed this head-on multiple times. He wasn't exactly known for being shy, and he didn't mince words here.
On the Full Send podcast back in 2022, he was asked point-blank about the rumor. He laughed it off and said, "The rumor ain't true. It's not even anywhere close to being true." He even went as far as to say he was never even romantically attracted to Kris. He liked her, sure, but as a friend.
"I was dating supermodels," he added. Kinda a flex, but it gets the point across.

He even posted a video on Twitter (now X) on Father’s Day in 2019 just to shut it down again. He talked about how proud he was of all the Kardashian girls, just like Bob would be, but he was firm: "She's not mine."
The Paternity Test Drama
You’d think a simple DNA test would end this. In earlier seasons of Keeping Up with the Kardashians, Kris actually tried to get Khloé to take one. She wanted to prove the haters wrong and give Khloé peace of mind.
Khloé’s reaction? She shut it down.
She was visibly upset and basically told her mom she didn't need a piece of paper to tell her who her father was. To Khloé, Robert Kardashian Sr. was her dad. Period. He’s the one who raised her, loved her, and whose name she carries. In her eyes, even questioning it felt like a betrayal of his memory.
- Robert's Stance: According to family friends and even his other ex-wives, Robert knew the rumors. Some people claim he had his own doubts. But even if he did, he never treated Khloé as anything less than his own daughter.
- The Alex Roldan Theory: If you want to talk about "lookalikes," many fans actually point to Kris’s old hairdresser, Alex Roldan. If you look at side-by-side photos of him and a younger Khloé, the resemblance is actually wilder than the O.J. comparison.
- The Bible Joke: Recently, in a 2025 episode of The Kardashians, Khloé and Kim actually joked about the O.J. rumors while looking at their dad’s old Bible. When Kim teased her about which "dad" the book belonged to, Khloé quipped, "Both of my dads!"
It shows she’s finally reached a point where she can laugh at the absurdity of it all.

Dealing with the Legacy of a Rumor
The "OJ Simpson Khloe Kardashian daughter" theory persists because it’s the perfect Hollywood "what if." It combines the most famous trial in American history with the most famous reality TV family.
But at the end of the day, biological or not, Khloé has made her choice. She identifies as a Kardashian. She honors Robert Sr. as her father every single year on his birthday and the anniversary of his passing.
If you're looking for a definitive "gotcha" moment where a secret lab report is revealed, you're probably going to be waiting forever. The family has moved on, O.J. has passed away, and the only person whose opinion really matters—Khloé—has already given her answer.
Actionable Insights for the Curious:
- Check the Timeline: Khloé was born in 1984. While the Kardashians and Simpsons were friends then, there has never been a shred of physical evidence (photos, letters, logs) suggesting an affair between Kris and O.J. at that time.
- Understand "Paternity" vs. "Fatherhood": The legal and emotional father of Khloé Kardashian is Robert Kardashian Sr. Even in the absence of a public DNA test, his name is on the birth certificate and he claimed her as his own until the day he died.
- Look for Recent Sources: Most "new" information regarding this topic comes from edited clips or social media speculation. Always look at the full context of their reality show episodes to see when they are joking versus making a serious statement.
The mystery is likely just a byproduct of a very public life and a very complicated family history. Sometimes, the simplest answer—that she just happens to look a bit different from her sisters—is the actual truth.
