The 31-year-old reality TV star called off her divorce from the basketball player after he almost died following a four-day drugs and alcohol binge in Las Vegas earlier this month.

However, she hasn't completely forgiven and forgotten as she has allegedly threatened to relaunch the divorce proceedings if he shows signs of falling off the wagon again.

A source told TMZ: "Khloé is annoyed by people on social media who are calling her a naive for dropping the divorce.

"She knows better than anyone about Lamar's battle with drugs. Feelings aside, she's game to drop the divorce party because Lamar has no one else in his life to help him."

The insider added: "Lamar is on the Kardashian health insurance policy and he needs to stay on."

The 35-year-old sportsman, who was found unconscious in a brothel, is currently recovering in a medical facility in Los Angeles after he was discharged and moved from Sunrise hospital in Nevada following signs of improvement.

Lamar - who reportedly suffered 12 strokes and is believed to be battling "major kidney failure" - is determined to get better for Khloé after she rushed to his hospital bedside as soon as she heard about his critical condition.

A source said previously: "Khloé has been highly encouraged by his motivation to overcome the hurdle of knowing he has a long battle of rehabilitation ahead.

"He's determined to get better for himself, for Khloé and for everyone else who has shown him love and support."

Khloé filed for divorce from Lamar last December after four years of marriage following allegations he was addicted to drugs and alcohol, and was sleeping around.
