Khloe Kardashian urged to get DNA test from friends

Rumors have been flying around that Khloe Kardashian is not the biological daughter of mogul Robert Kardashian, and now her friends are saying the reality star should get a DNA test.

The Chicago Sun-Times reports that Kardashian's friends are urging her to take the test. One insider says he wants her to take the test because  “It will just make this story go away — permanently."

If Kardashian doesn't take the test of her own accord, she could be under court order to do so. A legal source has said that should she decide to "file suit to prove the story is false, DNA testing will be demanded by attorneys from the other side, believing it will prove the story to be true," the Chicago Sun-Times continues.

Documents obtained by TMZ suggest a DNA test may not be needed. When filing for a 1999 annulment from second wife Jan Ashley, Robert Kardashian sent a declaration to the judge saying, "I decided that since I already had four biological children, I did not wish to have any more."

Upon hearing the rumor Kardashian tweeted on Wednesday just how upset she was, saying "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)."

Sister Kim Kardashian has also attempted to dispel the rumor. While leaving a hair salon Wednesday, Kim told E! Online, "Absolutely not!" The rumor is "Ridiculously false."
