Reports Surface that Khloe is Not a Kardashian

Could Khloe Kardashian not be an actual Kardashian? Reports are surfacing that the sister of the famous family may have a different blood line. INSIDE EDITION has the scoop.

"Disgusting." That's what Khloe Kardashian is saying today about a report that claims she is the result of an affair between her mom, Kris Jenner, and an unidentified man

A furious Khloe tweeted: "I let a lot of things slide but this one is really low. YOU ARE DISGUSTING! (yes you know who you are)."

Her anger stems from a bombshell report in the new Star magazine with a headline that reads: "Khloe is Not a Kardashian."

The magazine quotes Ellen Kardashian, the widow of famed O.J. Simpson lawyer Robert Kardashian, as saying that he told her Khloe was not his daugter just before he died in 2003.

Khloe has been dealing all her life with speculation that she's not a Kardashian. She's much taller than her sisters Kim and Kourtney.

On their reality show, an entire episode was once dedicated to Khloe wondering whether she was adopted.

A DNA test showed that Kris was her mom. But the show never raised the issue of her father's identity.

In her new book, All Things Kardashian, Kris admits to cheating on Robert Kardashian but says it was after her first four children were born. She writes of the affair with an unnamed and much younger producer: "I was in the middle of a raging affair. Wild crazy sex everywhere, all the time."

In her tweet Khloe denounces the Star magazine report: "The audacity you have to mention my fathers name like this!"

The ladies on The Talk reacted to the story.

Sarah Gilber said, "Whether he is or whether he isn't, she's a Kardashian. He raised her."

Sharon Osbourne said, "It's nobody's business."
