Khloe Kardashian Has Prepared Divorce Papers To End Marriage To Lamar Odom -- But She Won't 'Pull The Trigger… Yet'

Khloe Kardashian has prepared divorce papers to end her troubled marriage to Lamar Odom following secret talks with a lawyer, RadarOnline.com has exclusively learned.

"Within the last two weeks, Khloe instructed her lawyer to have divorce papers drawn up," a source with intimate knowledge of the situation revealed.

"All she needs to do is tell the lawyer to file the petition. She has even signed the divorce papers, in anticipation."

The pair's marriage -- in its fourth year -- has been rocked by claims the ex-NBA star was unfaithful with at least three women. Twenty-nine-year-old graduate student Sandy Schultz was the third woman to come forward to expose her affair with Odom, 33, after accounts by mistresses Polina Polonsky and Jennifer Richardson.

Though the source described Kardashian and Odom as being on the verge of divorce, the insider was insistent that the youngest of the three reality television siblings was not yet ready "to pull the trigger."

"But she feels she has no other options at this point because Lamar is unwilling to go to rehab," the source added.

"There is hope that if Khloe does file, Lamar will realize he must get help."

Another Kardashian family insider this week admitted the rough patch between the pair had grown to almost beyond repair.

"It’s like the situation is just too far gone at this point for a split to be anything but unavoidable," an insider said. "It doesn’t seem like a reconciliation is any closer to happening."

The 29-year-old E! star has been on a roller coaster of emotions since her husband's cheating and serial drug use was exposed: At one point, Khloe was so desperate to save her marriage that she considered getting pregnant as a last-ditch effort to stop her husband's destructive behavior.

Khloe "truly believed that if she got pregnant, it would cause Lamar to change his ways," a source said.

"Khloe thought having a baby together would bring them closer together as a couple. It was all she ever wanted, to have Lamar’s baby and have their own family."
