Khloe Kardashian reportedly wants nothing to do with Lamar Odom because he's allegedly started up his drug habit again.

Eight months after the former NBA player suffered a near-fatal drug overdose in a Nevada brothel, "he is using again," a source close to Kardashian told Us Weekly.

"So Khloe had to put her foot down and stop helping him out. She can't watch him fall apart again."

Kardashian, 31, stuck by Odom's side throughout the entire recovery process, however, she's not going to put up with a relapse.

Kardashian therefore kicked Odom out of the Calabasas, CA, home she had leased for him in the same neighborhood as her family, according to Us.

"More than anything, Khloe wants to be in Lamar's life," the source said, "but only if he gets healthy."

An Odom pal reportedly insists he's not doing drugs anymore, but the 36-year-old former basketball player was spotted drinking hard alcohol twice in the last several months -- the night before Easter Sunday with friends and then alone in LA's Beverly Center mall in May.

"He has definitely been partying," a second insider told the magazine.

As previously reported, the Keeping Up with the Kardashians star filed for divorce from Odom for the second time on May 26. Kardashian initially filed paperwork in December 2013 after four years of marriage, but she withdrew the documents from court once Odom's health crisis began in October 2015.

"It's not the future that you're afraid of," Kardashian tweeted earlier this week after the latest KUWTK episode aired and focused on her impending divorce. "It's repeating the past that makes you anxious."
