Transgender woman Chantel Spears - formerly Ronald Spears - claims the reality TV star `violently` attacked her outside a Hollywood nightclub on December 5 2009.
Papers filed by Chantal state that after the incident the victim needed medical care and suffered from `severe mental anguish` and also claimed Khloe struck her `in and about her body`. However, no arrests were made at the time of the incident.
Chantel - who is seeking unspecified damages - says the alleged assault happened after she made a comment to Khloe`s husband Lamar Odom.
She told website TMZ: `All I was telling Lamar Odom is maybe he is too young to get married and all of a sudden I get this big push from this girl.`
Although Khloe`s spokesperson didn`t comment, her friends insist she did nothing wrong.
One told Us Weekly magazine: `This was two years ago and Khloe did nothing. This person shoved Khloe and she pushed them off. This person just wants to jump on the bandwagon.`
