Khloe Kardashian Lamar Odom2*While most people would be out celebrating with their significant other on their fourth wedding anniversary, Khloe Kardashian opted for a solo trip to the gym without her wedding ring in sight.

Last week Kardashian’s Instagram stream indicated the reality star spent her anniversary  without estranged husband Lamar Odom, which stirred even more talk of the marriage falling apart.

The usual show-and-tell Kardashian posted zero pictures of presents from Odom, and instead flaunted shots of an engraved crystal her best friends Malika and Khadijah Haqq got for her.

“Khloe, Love You 4 Ever” the heart-shaped rock read.

Then Kardashian followed up with a cryptic photo with the caption, “I can’t explain and I won’t even try.”

There have been a series of subliminal messages that have suggested there is trouble in paradise for Odom and Kardashian. Recently Kardashian took her husband’s last name out of her Instagram and Twitter bios.

What once read “Khloe Kardashian-Odom,” now it only says “Khloe.”

A rep for Kardashian gave a statement refuting that her recent changes in social media had anything to do with her marital status.Khloe Kardashian Lamar Odom
