Khloe Kardashian plans to file for divorce in Los Angeles from professional basketball player Lamar Odom, her husband of four years, TMZ reported. The reality TV personality will cite irreconcilable differences in the legal documents she could file as early as Friday, the celebrity news website said. TMZ said the process of ending the marriage should be straightforward since the couple have a prenuptial agreement, which kept all their assets separate. They also have no children. Odom's alleged crack addiction and infidelity were the main reasons for the split, the report said.
