Khloe Kardashian -- Flaunting Lamar Odom Tattoo ... With Love

Another sign Khloe Kardashian isn't over Lamar Odom -- she Instagrammed a photo of her L.O. tattoo ... and punctuated it with a heart emoji in the caption.

The pic shows Khloe gripping her Bentley shift knob ... and showcasing the tat she got for Odom right after they got married in 2009.

Despite the fact they separated in 2013, Khloe has dragged her feet with the divorce -- and we're told she's still conflicted on whether she truly wants to end her marriage to the ex-NBA star.

This picture seems to support the theory that there's still hope for a reconciliation.
