Friday marks four years Khloe Kardashian and Lamar Odom have been married but it might not be a happy celebration. According to Hollyscoop, Kardashian is planning to file for divorce on her wedding anniversary.

There have been reports that the two were going to reconcile and spend their special day rekindling their romance but that's not what Kardashian has planned. According to Hollyscoop, a source told In Touch magazine that the reality star reached out to Odom one last time to try and save her marriage.

The 29-year-old reportedly wrote an ultimatum letter to her husband telling him that he needed to get his act together or she would spend their anniversary filing for divorce.

"Khloe is giving Lamar until their four-year wedding anniversary to show some sign he still wants to be in their marriage," the source said. "If not she's filing for divorce."

In the letter the source said the reality star let Odom know exactly how she's been feeling and told him that he had "put her through hell."

"She basically wanted him to know: 'I look great, I have an amazing life, I feel good about myself - so f*ck you," the source said.

Another source reportedly told the magazine that Kardashian is embarrassed by all the media reports and feels like she wasted her time trying to protect him and look after him through this difficult time and she's done trying to make things work.

According to TMZ, Kardashian and Odom did see each other the night before their anniversary. A source told the website that Odom left the Palm Springs house he has been staying at where he has allegedly been on "intense crack binge" and went to the Tarzana home he used to share with Kardashian.

Sources said he only stayed at the house for a "short time," had a conversation with his wife and then left heading back to his downtown Los Angeles apartment. The source has no idea what was talked about during their brief meeting but if Kardashian's Twitter page is any indication of how she's feeling it's safe to say the marriage could be over.

A couple days after removing Odom as her last name on Instagram, the reality star dropped the name from her Twitter account as well.
