LAMAR ODOM & KHLOE GET MATCHING TATTOOS! WHAT WE DONT GET IS WITH SO MUCH OF IT FOR FREE WHY PAY FOR IT?

Well at least something's finally official in the Khlomar "marriage": The couple got matching tattoos to signify their still-not-quite-legalized union.

According to Khloe's website, the couple stopped by Tattoo Mania in Los Angeles Saturday night on a whim and got tattoos of each other's initials on their hands.

Now if only this weren't the only permanent step they've taken so far ...

Update: We're told the total bill was $160 -- and the couple left more than a $60 tip.
