Khloé Kardashian is preparing to file for divorce from Lamar Odom for the second time.

The 31-year-old reality star will move to officially end her marriage from her estranged husband "soon," a source close to Kardashian confirms to ET. Another source close to Kardashian told ET that she "is moving forward with the divorce."

Kardashian and Odom, 36, married in 2009 after a month of dating and she originally filed for divorce in 2013, only to call it off following his drug overdose last year.

"I'm there helping him and I love him and I've always loved him," Kardashian explained of why she put the proceedings on hold in October 2015. "That will never change, and I just feel like it's a really insensitive thing to fast forward a divorce."

Kardashian supported Odom through his recovery after the former NBA player was found unresponsive in a room at the Love Ranch brothel in Crystal, Nevada. Their relationship hit yet another rocky patch in the past month after Odom was spotted at a bar reportedly ordering alcohol.

"He almost died -- if that's not enough to keep him sober, then what is?" a source told ET. "One thing is so clear -- Khloe would never get back with Lamar unless she knew 100 percent that he was maintaining his sobriety. Him drinking again is a huge slap in her face."

Earlier this week, Kardashian penned a lengthy essay about "letting go" on Instagram. "Letting go doesn't mean that you don't care about someone anymore," she wrote. "It's just realizing that the only person you really have control over is yourself."
