Khloe Kardashian and Lamar Odom Divorce: Lamar Hooked on Crack Cocaine, Cheated with Two Women

Khloe Kardashian-Odom and Lamar Odom's marriage have been on the rocks with rumors of infidelity and now new reports claim the problems run deeper than that. The 33-year-old NBA player has been struggling with a crack cocaine addiction for the past two years and they've reached their breaking point.

TMZ reported early Sunday morning Odom is addicted to crack cocaine. Sources say Lamar Odome went to rehab prior to the 2012-13 season and was clean during the season with the Clippers but picked up the habit again when it was over.

The couple have not been spotted together since June 2 and have not addressed divorce reports following tabloid accusations that the basketball pro cheated on Khloe with two women.

Odom allegedly checked into a rehab center in San Diego last August and Kardashian, 29, reportedly hired a private investigator to stand guard outside the center so Odom would not leave.

According to TMZ, Lamar Odom constantly threatened to check out but ended up staying for three weeks before leaving for good.

Meanwhile, Khloe does in fact believe that Lamar cheated on her, the site reported. Khloe is said to be focusing on saving Lamar now from his drug use, instead of worrying about their marriage.

"She didn't smile at all and seemed miserable," an eyewitness at Equinox gym in Woodland Hills said Thursday about Khloe. (Kardashian Odom has generally appeared to wear her rings to the gym in the past.) "She seemed like she had a lot on her mind."
