OTRC: Khloe Kardashian rants following paternity tabloid report, Kris Jenner calls it 'stupid'

Khloe Kardashian went on a Twitter rant on Wednesday following a tabloid report that suggested she is not the biological child of the late Robert Kardashian, while her mother and his ex-wife, Kris Jenner, called the claims "stupid."

Khloe Kardashian, 27, is taller than her sisters Kim, 31, and Kourtney, 32, and bears little resemblance to them. She was even seen seeking a DNA test on an episode of the family's hit E! reality show, "Keeping Up With The Kardashians."

Star magazine quoted Jan Ashley, Robert Kardashian's second wife, as saying that he had told her that Khloe Kardashian is "not really a Kardashian." It also quoted Ellen Pierson, his third and latest spouse, as saying that "Robert did question the fact that Khloe was his." The story was also posted on Radar Online, whose parent company owns Star.

"The audacity you have to mention my father's name like this!," Khloe Kardashian Tweeted. "Should be ashamed of urself! I let a lot of things slide but this one is really low... YOU ARE DISGUSTING! (yes you know who YOU are)"

Robert Kardashian, a lawyer, died at age 59 in 2003 after battling cancer. He and Jenner, his first wife, were married between 1978 and 1990. The two also have a son, Robert, who is 24. Jenner also has two daughters, Kylie and Kendall, with current husband Bruce Jenner.

E! Online quoted Kris Jenner as saying that the claims printed by Star are "so stupid. All so silly. Just another day!!!"

In a 2009 episode of "Keeping Up With The Kardashians," Khloe Kardashian is seen seeking a DNA test to find out if Kris Jenner is her birth mother. She talks about how she feels her mother treats her differently than her sisters, namely Kim and Kourtney, adding "someone that psychotic cannot be blood related to me."

She orders a DNA home testing kit and is seen inserting a Q-Tip into her mother's mouth.

"Like, I have boundaries! Warn me!" Kris Jenner says, and then tells Bruce Jenner about the incident.

"Khloe has a tendency to be very dramatic and over the top," he says.

Khloe Kardashian then shows her mother what appears to be the results of a DNA test.

"You have a child," she says, smiling.

"Khloe, I was there when you were born," Kris Jenner tells her, adding that she went through "a lot of pain that day and you're still getting on my nerves. I love you very much."

Khloe Kardashian's E! reality show spin-off "Khloe & Lamar," which showcases her life with husband and NBA star Lamar Odom, returns for a second season on February. The two filmed episodes for it in Dallas. Odom was traded from the Los Angeles Lakers to the Dallas Mavericks late last year.
