Khloe Kardashian's marriage to Lamar Odom over? Reality star drops his surname on Instagram

Monday morning saw the star tellingly drop her basketballer husband's surname from her Instagram account, now simply going by her maiden name on the social networking site.

But later that same evening, the 29-year-old was spotted heading to dinner at a steakhouse in Topanga Canyon, California, wearing her wedding ring.

 The mixed signals on Monday follow reports that her marriage is on rocky ground due to the NBA player's alleged drug abuse.

Lamar hasn't been seen for several days and is reported to be holed up in his downtown LA residence, which is a 45 minute drive from the mansion he shared with Khloe in Tarazana.

Last week there were several reports that a split will be announced soon, but no announcements have been made yet.
