It may be Khloé Kardashian and NBA player Lamar Odom's fourth wedding anniversary, but the reality star doesn't seem to be celebrating.

Instead, the "Keeping Up with the Kardashians" star, 29, dropped "Odom" (and "Kardashian") from her Twitter bio. (Earlier this week, she did the same thing to her Instagram profile.)

Though her rep has yet to respond for a request for comment, earlier this week, she explained the Instagram bio change as follows: "She took off Kardashian and Odom on her bio only. Her Instagram handle has ALWAYS been just Kardashian to match her Twitter name - so both of her names are @KhloeKardashian. They always have been but, yes, in her bio she removed both of her last names. So it simply says Khloé."

The changes come at a tumultuous time for the couple, who have not been photographed together since Odom, 33, was arrested for DUI. Since then, Odom has slammed reports that he has a drug problem.

Still, People magazine reported that Kardashian "still wants to save their marriage."

"She wants him to get better, but there is a lot to work out," a source told the magazine. "She's taking everything one day at a time and concentrating on herself. Everything with Lamar is very unclear."
