The biggest celebrity news in the past couple weeks is that Khloe Kardashian is expecting a girl and O.J. Simpson has finally confessed to the murders of ex-wife Nicole Brown Simpson and her friend Ronald Goldman.
As both of these individuals are making headlines once again, the rumor mill is bringing back a question that surfaced decades ago: Is Simpson Khloe's biological father?
Simpson even publicly addressed that he has no connection with the reality star, despite their resemblance.
"I don't think for me, I have nothing to do with it," Simpson told TMZ. "I would be proud ... but trust me, I had nothing to do with it."
O.J. Simpson doesn't have the greatest record for telling the truth, so die-hard Kardashian fans are still speculating about the authenticity of his claim.
The disgraced former football player has five of his own children, all of who don't even bear a slight resemblance to the Kardashian, but there seems to be a lot of circumstantial evidence out there that may gave us clues to understanding both sides of the argument.
Here's how the rumors got started, and it might leave you questioning everything by the end...
The Rumors
Before Kim Kardashian's sex tape propelled her and her family into the limelight, the family was well-known only because of their relation to Robert Kardashian Sr.
The talented lawyer was part of the "dream team" that defended Simpson while he was on trial for murder.
As Khloe grew up, she was much taller than her petite older sisters, her hair was lighter and curlier, and she had a different body shape.
So even before Keeping up with the Kardashians, there were a lot of people who weren't convinced on who Khloe's real father is.
People already had these speculations, and then sources started coming forward adding fuel to the fire.
Kris Jenner's former husband's ex-wives denied Khloe's heritage, claiming that Robert Sr. was skeptical about whether his youngest daughter was his.
"Khloe is not his kid - he told me that after we got married," said Jan Ashley, who married Robert Sr. after he divorced Kris.
Kris also admitted that she cheated on her ex-husband while they were married, which many believed to have been with Simpson, since they were in close contact.
The Real Story
Although Kris cheated on her husband, she confessed it wasn't with Simpson.
Khloe has remained strong throughout these years, and has used humor as a way to respond to these "outrageous" claims: "I don't know... Some days I'm O.J.'s daughter. Others, I'm Robert's daughter," she wrote in her post where someone commented on why she looked "white."
Khloe says she knows who her true family is, and a paternity test wouldn't change anything.
"My dad is Robert Kardashian. My other dad is Bruce Jenner," she told her mom. "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."
