Khloe Kardashian drops her Lamar Odom’s surname on Instagram

On Monday Khloe Kardashian dropped her Lamar Odom’s surname from her Instagram account, now simply going by her maiden name on the social networking site.

Later that same evening, Khloe Kardashian, 29, was spotted heading to dinner at a steakhouse in Topanga Canyon, California, wearing her wedding ring.

She seemed to be in a pensive mood as she valeted her car outside of her dinner destination.

Showing off her newly slim frame, Khloe Kardashian sported white denim trousers and a low-buttoned black shirt as she wore her ombre tresses in flowing waves over her shoulders.

The mixed signals on Monday follow reports that Khloe Kardashian’s marriage is on rocky ground due to Lamar Odom’s alleged drug abuse.

Lamar Odom 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 Kardashian in Tarazana.

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

Meanwhile, Radar has claimed that Khloe Kardashian won’t decide the fate of her marriage to her husband until after she is done filming Keeping Up With the Kardashians.

The reason is said to be because Khloe Kardashian doesn’t want to discuss a decision to divorce on the E! reality show.

“Khloe is steadfast, that she won’t decide whether she wants out of the marriage until she is done shooting the current season of the … show,” a sources tells Radar.

“She has been through so much the last year with Lamar, and Khloe just doesn’t want this to be played out in front of the cameras.

“It’s a very sensitive situation, she is being a trooper and is being a total professional while shooting.”
