0911_khloe_kardashian_ring_akm-gsiKhloe Kardashian wants everyone to know … she”s not abandoning her husband Lamar Odom in his time of need … and proudly sported her wedding ring out last night to show her commitment.

Khloe — along with Kylie, Kendall, Kourtney and Scott Disck — hit up a sushi joint in Calabasas last night while Lamar was out buying scrubbing pads that some people use in makeshift crack pipes.

On her way out of dinner, photogs snapped away as Khloe had a smile on her face and her 12.5 carat diamond ring on her wedding finger.

Earlier Tuesday, KK retweeted the words, “Sometimes you just gotta be your own hero and save your own little heart. Because sometimes, the people you can”t imagine living without, can actually live without you.”

Just this afternoon, she wrote: “I see the pain in your pride.”

As we reported … Odom has denied having a drug problem, insisting “life is good.”
