Khloe always noticed she didn't look like her siblings ...

It didn't take Khloe Kardashian long to respond to her former stepmothers Jan Ashley and Ellen Pierson Kardashian after they leaked personal information about her parentage.

Star magazine and Radaronline, both publications operating under the American Media umbrella, published a shared exclusive story that quoted the late Robert Kardashian's ex-wife and widow.  They allege that Robert Kardashian long suspected that Khloe's biological father is someone who had a fling with Kris Jenner during one of her extra-marital affairs.

Khloe lashed out on her Twitter page.  She didn't dispute what the two women said, but took exception to their loose lips:

There has been no word yet from the family matriarch.  Kris Jenner has been at Planet Hollywood Resort and Casino in Las Vegas this week where she is a judge for the 2012 Miss America pageant - pics here.
