Khloe Kardashian Files Divorce Docs

Khloe Kardashian has just filed court documents to divorce Lamar Odom and restore her name -- TMZ has learned.

As we first told you, Khloe planned to pull the trigger today on her 4-year marriage to Lamar, who has been deep in the world of drugs on and off for the last 2 years.

In the legal docs, filed by disso-queen Laura Wasser, Khloe cites "irreconcilable differences."

As we previously reported, the couple has a prenup so division of property will be a cinch -- they kept all their property separate.

And Khloe is asking the judge to take Odom out of her name, so she is once again simply Khloe Kardashian ... eliminating Odom from her life in every way.

And, Khloe is NOT asking for spousal support and wants the judge to reject any bid by Lamar for the same.
