Khloe Kardashian defended by mom on paternity claims

(CBS) Reality TV matriarch Kris Jenner came to the defense of her daughter Khloe Kardashian Odom Thursday, slamming rumors that the late Robert Kardashian was not Khloe's father.

"I've never heard such crap in my life," Jenner said on "Good Morning America." "I gave birth. I know who the dad was."

She was responding to reports in Radar Online this week that two of Robert Kardashian's ex-wives have claimed he told them Khloe was not his child.

Referring to an episode of "Keeping Up With the Kardashians" that addresses just such speculation, Jenner said, "It's the family joke because Khloe was blonde and not dark-haired. ... Get a life."

Khloe, who also is taller than her siblings, tweeted about the reports Wednesday. "The audacity you have to mention my father's name like this! 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)"

A former model, Khloe, 27, is married to basketball player Lamar Odom and is involved in her family's reality TV shows. She also is a partner with her older sisters, Kourtney and Kim, in the fashion retailing businesses.

The three sisters have a brother, Rob Kardashian; two half-sisters, Kylie and Kendall Jenner; three stepbrothers, Burt, Brandon and Brody Jenner; and a step-sister, Casey Jenner.
