Khloe Kardashian Still Wearing Wedding Ring -- I'm Sticking with Lamar ... For Now

Khloe Kardashian hasn't given up on her marriage to Lamar Odom ... at least publicly ... because she's still wearing her wedding ring.

Khloe was on her way out of a medical building in L.A. Monday when the photo was taken -- and while it's obvious she was trying to hide her face, she was clearly NOT trying to hide her symbolic commitment to her husband.
