The internet just won’t let it go. For over two decades, the identity of Khloe Kardashian’s dad has been the subject of more conspiracy theories than the moon landing. If you spend five minutes on TikTok or scroll through old Reddit threads, you’ll see the side-by-side photos. You’ll see the charts comparing earlobes and jawlines.
Honestly, it’s a lot. People point to Khloe’s height, her lighter hair, and her facial structure, claiming she looks nothing like Kourtney or Kim. But does a lack of physical resemblance actually prove a family secret?
The truth is way more nuanced than a grainy collage. While the tabloid rumors have named everyone from O.J. Simpson to a family hairdresser, the real story involves a complicated mix of DNA tests, a mother’s admitted infidelity, and a man who refused to be anything less than a father until the day he died.
The Robert Kardashian Legacy
Robert Kardashian Sr. wasn't just a famous attorney on the "Dream Team"; he was the rock of the Kardashian family. He married Kris Jenner in 1978, and they had four kids: Kourtney, Kim, Khloe, and Rob. By all accounts, Robert worshipped his children.

Even after the couple's messy 1991 divorce—sparked by Kris’s affair with soccer player Todd Waterman—Robert stayed deeply involved. When the paternity rumors first started leaking into the press years later, it wasn't Khloe who brought them up. It was actually Robert’s later wives, Jan Ashley and Ellen Pierson.
They claimed Robert had "confided" in them that Khloe wasn't his biological child. Naturally, the Kardashian sisters fired back, calling these women "shameful" for trying to tarnish a dead man’s name for a paycheck. Robert passed away in 2003 from esophageal cancer, and he never once publicly questioned if Khloe was his. To him, she was his daughter. Period.
Why Everyone Points to Alex Roldan
If you look up Khloe Kardashian dad rumors, one name pops up more than anyone else: Alex Roldan. He was Kris Jenner’s hairdresser for years.
The "proof" theorists use?
- Height: Khloe is significantly taller than her older sisters.
- Bone Structure: Before her well-documented plastic surgery, fans argued she was a "dead ringer" for Roldan.
- Middle Name: Her middle name is Alexandra. People think that's a "clue."
Kylie Jenner even joked about this on Twitter years ago, posting a photo of Khloe and Alex with the caption, "First official photo of my sister and her dad!" She later clarified it was a joke, but the internet never forgot. Kris Jenner has consistently denied that Roldan is the father, and Roldan himself has never claimed paternity.

The O.J. Simpson Theory (and Why It’s Dead)
Then there’s the O.J. factor. Because Robert Kardashian was O.J.’s close friend and lawyer, and Kris was best friends with Nicole Brown Simpson, the "secret affair" narrative was easy for tabloids to sell.
O.J. Simpson himself finally addressed this before he passed away. In a 2019 video, he straight-up said he never had a romantic or sexual interest in Kris. He was "very proud" of Khloe but insisted he was not her father.
Recently, on an episode of The Kardashians in late 2025, Khloe and Kim actually joked about the "two dads" rumor while looking at Robert Sr.’s old Bible. It’s reached a point where the family just uses the gossip for comic relief. If Kris Jenner was really hiding a secret with O.J., she certainly isn't acting like it now.
What Do the DNA Tests Actually Say?
You’d think a simple swab would end this. In earlier seasons of Keeping Up With The Kardashians, the family actually tried to do DNA testing.
Interestingly, Khloe initially refused a paternity test. She said, "I don't need someone to tell me who my family is." For her, Robert Kardashian was her father because he raised her. However, they did eventually do some genetic testing on the show.

One test confirmed that Khloe is indeed Kris Jenner’s daughter (debunking an even wilder "adopted" theory). Another more recent genetic breakdown showed Khloe had a high percentage of Middle Eastern DNA, which aligns perfectly with Robert Kardashian’s Armenian heritage.
The most recent "proof" came from a surprising place: Khloe’s son, Tatum. Kris Jenner has pointed out that Tatum looks exactly like a "mini-me" of Robert Kardashian Jr. (Khloe's brother). In the world of genetics, these "rebound" traits often skip a generation and then come roaring back, suggesting the Kardashian DNA is very much present in Khloe's line.
The Reality of Being "Different" in a Famous Family
It sucks to be the "different" sibling. Khloe has talked openly about how the constant questioning of her paternity affected her self-esteem. She was the "tall, curly-haired one" in a family of petite, olive-skinned women.
But genetics are weird. You can have two siblings who look like twins and a third who looks like a distant cousin. It doesn't mean a scandal is afoot; it just means the genetic dice rolled differently.
Kris Jenner admitted in her memoir that she cheated during her marriage to Robert. She called it her "life's biggest regret." That admission is what keeps the fire burning for conspiracy theorists. If she cheated once, they figure, she could have cheated at the time of Khloe’s conception. But until a verified DNA test says otherwise, the paperwork—and the man who signed the birth certificate—says Robert Kardashian is the father.
Actionable Insights for Fans and Fact-Checkers
If you're trying to navigate the sea of Kardashian rumors, keep these three things in mind to stay grounded in fact:
- Follow the DNA, Not the Photos: Physical resemblance is a poor indicator of paternity. Focus on the 2018 23andMe results shown on the show, which confirmed Khloe's Middle Eastern/Armenian ancestry.
- Respect the "Social Father" Concept: In family law and psychology, the man who raises, loves, and supports a child is the father. Khloe has made it clear that Robert Sr. earned that title every day of her life.
- Vetting Sources: Be wary of claims made by Robert's later wives (Jan Ashley and Ellen Pierson). They were in legal battles with the Kardashian kids over Robert’s estate, giving them a clear financial motive to sell scandalous stories to tabloids.
