It looks like things have gone from bad to really, really ugly in a very short time for Khloe Kardashian and her estranged husband, Lamar Odom. Even though she's been by his side ever since he almost died of a drug overdose at a Nevada brothel back in October, the reality star apparently took a swipe at him on her Instagram account on none other than Father's Day this weekend.

Khloe shared an Instagram quote that said, "'You don't know what you got till it's gone.' I say, you knew what you had, you just never thought it could slip away."

She added, "We often take for granted the things that deserve our gratitude the most. We do this with both people and material possessions. The problem is many people do not realize this until it is too late. We take things for granted on a daily basis, always with the assumption that whenever we need something, it will be there. There are so many things that we fail to realize the true value of until they are missing from our lives. Sadly. (sic)"

According to Xpose on Sunday though, the post is now gone. This comes only a few days after Kardashian filed for divorce for a second time from Odom. Even though they initially split back in December of 2013, their divorce was never finalized due to a backlog of paperwork in the Los Angeles county court system.

And while there were a few rumors floating around that Kardashian and Odom have reconciled, that might have been very brief because the reality star is working full speed ahead in assuring that her marriage is finalized as quickly as possible as she wants to move on with her life, according to Kardashian family sources.
