Khloe Kardashian, Lamar Odom -- Divorce Will Be Simple

Khloe Kardashian wants to divorce Lamar Odom -- even though she hasn't pulled the trigger -- and there will be NO disputes because everything is predetermined by their prenup ... TMZ has learned.

Sources close to the couple tell us ... Khloe is "anxious" to end the marriage but, as we first reported, she hasn't had papers drawn up because she fears it could push Lamar over the edge -- she's worried he'll OD or commit suicide.

But we're told Khloe is waiting for the right time to make her move, and when she does the divorce will go without a hitch. That's because the prenup keeps the assets of Khloe and Lamar separate ... sources familiar with the document tell TMZ.

In fact, we're told Lamar is so deep into the world of drugs, he's in no position to start haggling, even if there were something over which to haggle. As we reported, Lamar has been using crack off and on for months, among other drugs, and is probably legally incompetent to negotiate anything.

One more thing. There are stories floating around that there's an "infidelity clause" in the prenup, giving Khloe more money if Lamar had cheated. All of our sources make it clear -- NO SUCH CLAUSE is in the prenup.
