Khloe Kardashian's marriage to Lamar Odom may well be over if sources speaking to two US entertainment websites are correct. It appears Odom has been battling with substance abuse issues and this has, allegedly, exacerbated pre-existing marital issues.

Although this may be news to us, it certainly hasn't come as any surprise to those close to the couple, according to sources speaking to TMZ. It appears Kardashian encouraged Odom to visit rehab last August. It seems Odom was unwilling to tackle his problem as Kardashian hired detectives to follow her husband's movements whilst in the San Diego facility. It seems Odom made numerous attempts to leave and did so after three weeks. Odom, according to the report, did maintain a sober lifestyle for a while, managing to play well in his final season with the Los Angeles Clippers.

It seems the situation has worsened and the Kardashian/Jenner/Odom family have hosted an intervention in the hopes Odom will alter his lifestyle and enter rehab. The NBA player seems uninterested in his family's concern or ideas. According to a source speaking to People, Kardashian only "recently came clean and [her family] has been trying to help since."

However, this help may not be enough as Odom is, according to sources, in denial. A source addressing People said "Lamar genuinely doesn't think he has a problem, it's all 'work hard then party hard' with him until it goes off the rails. They really do love each other. But she really feels that this problem is out of control, and she's hurt that he won't get help."

Until the 32-year-old admits he has a problem, it appears Odom and Kardashian are taking a short break from one another's company. Photographs, obtained by People, show Odom leaving the house he shares with Kardashian. A friend can clearly be seen placing a large suitcase into Odom's car, whilst the NBA player watches. 

The reports of drug addiction could not have come at a worse time for the couple. Odom has recently been associated with a number of women who claim to have slept with the NBA player. Kardashian may not be giving up on Odom but she might be prepared to end their marriage, according to sources speaking to TMZ and People respectively. One source claims "Khloe is more concerned about saving Lamar than ending her marriage." Whilst another focussed on Kardashian's feelings saying "it's a really hard time for Khloe. She's kept this secret for almost two years trying to save Lamar and their marriage." Another source emphasised Kardashian's willingness to focus on her husband's health and not the state of their marriage: "whatever they're going through in their relationship is taking a back seat to getting him better, I can tell you that."

Neither Odom nor Kardashian's representatives have commented as yet on the rumours of divorce and drugs. Kardashian has responded to Twitter, albeit indirectly, writing (amidst profanities) "shame on you, "you" addressing those who "talk sh*t about my family!"
