The pair first filed for divorce in 2013, but the Keeping up with the Kardashians star called off the divorce in October of last year after Odom suffered an overdose.
"This is a very delicate and difficult time for both Lamar and Khloé, and the most sensible thing to do at such a time is not make any big moves and put everything on hold," a source told WHO at the time. "So that's what she is doing."
