Is O.J. Simpson Khloe Kardashian's biological father? So say some theorists, who point to Khloe's resemblance to O.J.'s daughter with Nicole Brown, Sydney Simpson, as proof of the reality star's true parentage. In her memoir, Kris Jenner opened up about having an affair during her marriage with Robert, and O.J. was a family friend -- Robert was even one of his attorneys during his murder trial. Adding to the rumor, Robert's second wife, Jan Ashley, told Star Magazine that Robert confessed to her before his death that Khloe was not his daughter. "Khloe is not his kid. He told me that after we got married," she said. Robert's third wife, Ellen Kardashian, also gave credit to the rumor, telling Star, "Robert did question the fact that Khloe was his."
Prince Harry has also been the target of rumors questioning his pedigree. Princess Diana had an affair with redhead James Hewitt during her marriage to Prince Charles, and the rumor mill has long questioned whether James could be the Party Prince's real papa. But Diana's brother, Earl Spencer, has red hair too, so theorists, take heed!
