Khloe Kardashian Father Rumors: Dad Candidates According to Rumors

Khloe Kardashian's parentage has long been the subject of speculations, despite her mom Kris Jenner's insistence that her first husband, the late Robert Kardashian, is Khloe's biological father.

And now, the prickly subject has reared its controversial head once more as reports emerged alleging that a certain singer is actually Khloe's real dad.

While we're on the issue, let's take a look at the "dad candidates" rumors have tipped as Khloe's biological father.

Lionel Richie

He's the latest name dropped by an insider, who insisted that he may have sired Khloe when he had a fling with Kris back in the day, as noted by the Daily Mail.

"They had a sexual affair - he bragged about it," the mole, who is also said to be a friend of Lionel's, revealed. "He said he was on the outs with his wife at the time."

"Everyone was sleeping around with everyone else back then, and Kris was hot in those days," added the source, who also observed that the singer's biological child, Sofia, somehow looks like "Khloe's little sister."

Meanwhile, in a reporty by RadarOnline, Khloe commented that she "had so many dads my head is spinning."

With that, let's move on to the other "dads."

O.J. Simpson

Last year, the NFL player's manager insisted that the incarcerated athlete is Khloe's real father.

"It's all going to come out sooner or later," Norman Pardo was quoted by New York Daily News as saying. "Khloe could be O.J.'s kid."

"They all took their vacations together. There was a lot of partying going on back then," Pardo added. "Kris cheated on Robert - she was known for having a good time."

The deceased Kardashian patriarch was O.J.'s attorney during the headline-grabbing murder trial in 1995.

Meanwhile, Kris has dismissed the claims as "crap," saying that she knows full well who Khloe's father is.

"I was there, right. I gave birth, I know who the dad was. Everything's good. We're all good," the momager said. "It's the family joke because Khloe was blond and not dark-haired. People just ... get a life."

Alex Roldan

Early in 2012, Khloe's half sister, Kylie Jenner, posted a photo of the 30-year-old posing with a man believed to be her dad.

The image made entertainment news headlines, as expected. However, Kylie later clarified that the information she shared was actually "a joke," as reported by abc7.com.

"Roldan is a hairdresser who worked with Kris Jenner in the past. He was named as Khloe's in several tabloid reports earlier this year, much to the annoyance of Khloe and Kris Jenner," the site explained.

With all these paternity rumors circling about, it's a wonder Khloe has not gotten a DNA test to put the allegations to rest. She did, however, explain why during an episode of "Keeping Up With the Kardashians" in 2012.

"I don't need someone to tell me who my family is. I have had the blessing of having two phenomenal fathers. I don't need a DNA test to prove who my father is," RadarOnline quoted Khloe as saying. "Seriously, my dad is Robert Kardashian. My other dad is Bruce Jenner."
