KHLOE KARDASHIAN BEING SUED FOR ATTACKING TRANSGENDERED WOMAN: KHLOE KARDASHIAN is being sued by a transgender woman who claims the reality TV star "violently" attacked her outside a Hollywood nightclub in 2009.

Chantal Spears, formerly Ronald Spears, tells TMZ the incident occurred after she made a comment to Khloe's husband LAMAR ODOM. Chantal says, "All I was telling Lamar is maybe he is too young to get married and all of a sudden I get this big push from this girl." Chantal alleges that she needed medical care and suffered from "severe mental anguish" afterwards. She is seeking unspecified damages.

Speaking of Khloe ... cameras caught her bravely venturing out in public minus her make-up over the weekend.

Meanwhile ... she and Lamar have been named the Happiest Celebrity Couple of 2011 by the gossip site Celebuzz. According to a market research firm they used, Khloe and Lamar received more positive buzz than any other couple this year.

Mentions of them as a couple were 92% positive. The words and phrases most commonly used to describe them were "love", "happiness", and "true love."
