It looks like fans might now know why Khloe Kardashian has decided to pull the plug on her marriage to Lamar Odom for the second time in a row. Apparently, the reality television star might have thrown in the towel after new reports indicate that the former NBA star might have gone back to his old habits.

According to Naughty Gossip on Friday, friends in his inner circle allegedly say that Odom might be back on "hard drugs." In fact, sources tell the publication that they recently confronted him and questioned him about crack pipes that have been located at his home.

Odom's life has spiraled out of control in recent years. Back in October, he was found nearly unconscious at a Nevada brothel after a three-day drug binge that almost killed him. He spent several months after the incident at a Los Angeles-area hospital, where friends and family were worried that he would never be able to walk and talk on his own again.

If that weren't enough, multiple insiders also say that Odom has been acting very "strange" and that his friends are convinced that he's "off the wagon." In fact, Odom was photographed by the paparazzi having a drink at a bar with friends before attending Sunday Easter mass with the Kardashian family last April.

Kardashian, meanwhile, put the ex-couple's divorce on hold during Odom's hospitalization. Although there were rumors that suggested the couple was considering getting back together again, she filed for divorce at a Los Angeles courthouse late last month.
