Khloe Kardashian has yet to comment about divorce rumors surrounding her husband Lamar Odom, but the reality star recently dropped "Odom" from her last name on Twitter.

The change came recently as the 29-year-old's name used to read "KhloeKardashianOdom." The couple's fourth anniversary is Sept. 27, but no word if they will be reconciliating or officially calling it quits. 

Khloe previously dropped Odom from her Instagram last week. 

Seems as if alcohol, drug abuse and cheating rumors may have caused problems for the couple. A source told People magazine that Khloe wants to still work things out with her husband despite his problems. 

"She still wants to save their marriage; she wants him to get better, but there is a lot to work out," the source said. "She's taking everything one day at a time and concentrating on herself. Everything with Lamar is very unclear."

The source added  that although the couple are now living separate lives, Khloe did not see hints of a troubled marriage.

"She never thought she would be in this position," the source said. "Two years ago she would have thought they'd be happily married with kids. It's been so hard to carry this secret and try to save not only Lamar but their marriage. It's taken a toll but she's one fierce lady." 

Meanwhile, Lamar took to Twitter for the first since July 12 to address his father Joe Odom, who told reporters that Khloe and her family cursed the basketball player. 

"He disrespecting the ONLY FAMILY that has loved me without expecting anything in return. They are the ONLY ones that have been here consistently 4 me during this dark time. Only person 2 blame is myself," Lamar tweeted this week. 

Lamar has yet to be resigned to a NBA team for the 2013-2014 season.
