Is Khloe Kardashian's marriage to Lamar Odom over?

Reality star drops his surname on Instagram... but then keeps everyone guessing by leaving her wedding ring ON

Is it over? Khloe Kardashian tellingly dropped her husband Lamar Odom's surname from her Instagram account on Monday

Where Khloe Kardashian stands with her troubled marriage to Lamar Odom appears to be changing not just by the day but by the hour.
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.

Showing off her newly slim frame, Khloe sported white denim trousers and a low-buttoned black shirt as she wore her ombre tresses in flowing waves over her shoulders.
Adorning her ears were large gold hoop earrings as she accented her features with smoky eye make-up.

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.
