For years now, there have been rumors flying around about how Robert Kardashian was not Khloé Kardashian’s biological father. Instead, a conspiracy theory has suggested that O.J. Simpson, who was once a close family friend of the Kardashians, is actually Khloé’s dad.

It’s not really clear where the rumors first started, but they’ve picked up so much steam over the last couple years that Khloé herself was basically forced to address them head-on last summer after people bombarded her Instagram page with comments about O.J. She didn’t have a whole lot to say about people continuing to buy into and spread the rumors, but she said “people are assholes” in reference to all of the comments that suddenly popped up on her IG page after O.J. was granted parole in Nevada following a lengthy prison sentence.

O.J. himself has seemingly refused to shut the rumors down in the past. In fact, back in 2016, reports emerged about how O.J. was pushing for a paternity test to take place to see whether or not he was actually Khloé’s real dad. It led to further speculation surrounding the situation.

But on Sunday afternoon, the paparazzi caught up with O.J. as he watched the Bills playoff game in Las Vegas, and he appeared to deny the conspiracy theory about him being Khloé’s dad. While he didn’t necessarily come right out and say that, the paparazzo who spoke with O.J. started the short interview off by saying, “Are congratulations in order?” O.J. responded by saying, “For what?” And after the paparazzo pointed out that Khloé recently announced her pregnancy with Tristan Thompson, O.J. laughed before explaining that, while he’s happy for Khloé, he isn’t the one who deserves any congratulations.
