Khloe Kardashian is now single, at least on Twitter.

Khloe, apparently, dropped Lamar Odom's surname and stopped using it on the popular social networking site. What is more? Khloe changed her profile name on Twitter on the very same day that the estranged couple celebrates their fourth wedding anniversary.

Khloe and Lamar married on Sept. 27, 2009. It was exactly a month after the two met. After their marriage, Khloe immediately changed her name from Khloe Kardashian to Khloe Kardashian Odom.

It sure looks like the couple will not be patching things up anytime soon. As you can recall, Khloe kicked her NBA star husband out of their home due to his excessive addiction to crack. They have been both living separately.

Lamar Odom's addiction has gone out of hand that it has been reported that the basketball player spent around $800 daily, over the summer, to support his addiction. TMZ has reports about the allegation. Furthermore, TMZ even pictured Odom buying scrubbing pads from a pharmacy, which are said to be the main ingredients for homemade crack pipes. Odom's addiction is the root cause why Khloe evicted him from their house. Ever since then, the couple's been living separately. It sure looks like they are clearly on the verge of separation.

Prior to dropping "Odom" on her Twitter profile name, it has also been reported that Khloe also dropped the surname from her Instagram account.

According to TMZ, Lamar, supposedly, had big plans to celebrate their 4th year as a married couple. Well, it appears that the feeling isn't mutual.

If Lamar is not really getting any better, Khloe has a lot of reasons to stay away from him. Their marriage will remain wallowing if Lamar shows no signs of improvement. The 29-year-old reality star could only hope for the best and seek support from her family and her followers from social media sites.
