Khloé Kardashian and Lamar Odom are officially ending their marriage, TMZ reports, with Khloé filing for divorce a second time today. The reality star cited irreconcilable differences, though TMZ notes the two are on good terms. Khloé first filed for divorce from Lamar in December 2013; she dismissed that petition last October after Lamar overdosed at a Nevada brothel. She made hospital decisions for him then and has helped take care of him as he recovers.
