Though Khloe Kardashian will never admit that anyone but the late Robert Kardashian could be her father, O.J. Simpson's daughter Sydney has been rumored to look quite like the "Keeping Up With The Kardashians" socialite.

Gossip surrounding Khloe Kardashian's paternity surfaced when two of Robert Kardashian's ex-wives alleged that the man who gave the reality star her famous last name did not believe he was her real father.

Then the rumor that O.J. Simpson could be her real father exploded, especially when side-by-side pictures Sydney and Kardashian were compared.

The story first broke in the beginning of the year, but has begun to take flight again now that Simpson allegedly changed his will to include Khloe Kardashian, as a National Enquirer article reported.

A source close to the Kardashians told the Daily Mail in January, "This is ridiculous and laughable."

But months after the gossip over Kardashian's ancestry began, the tale is beginning to pick up speed again.

Kris Jenner, her mother, tweeted a nonchalant post about the rumor, "Thanks for all your love and support today dolls! Wow some of the stories out there today are either fabricated, or SO 24 years ago!! LOVE U."

"O.J. told me Khloe's his child," an "insider" reportedly told the National Enquirer.

"It was the big secret that no one in the two families would discuss," the source told the tabloid. "And Robert admitted he and Kris were not having sex at the time Khloe was conceived.

"He [Simpson] used to tell us way back -- even before he and Nicole got divorced -- that he had a love child with the wife of a wealthy family."

But at the time of Khloe's birth, it would have been devastating for the news to come out that an American sports hero and actor had fathered a love child.

"O.J.'s career as a product spokesman -- which earned him well over $10 million -- could have ended and he always worried that his children would find out some day and become very angry with him."

Some tweeters believe that Simpson's daughter and Kardashian look similar:

"GO LOOK AT PICTURES! google sydney simpson & khloe kardashian next to each other ! they look so alike," @legit_mab wrote.

"also if u put a pic of her and Sydney Simpson side by side, they look like twins! But hey whatever's whatever," @SammyMojito tweeted.

"Khole and OJ Simpson Daughter Sydney they look just alike," @DYNAMICDST2 posted.

"Sydney Simpson and @KhloeKardashian could be twins!" @lylahbailey tweeted to the reality star.
