"Mob Wives" star Renee Graziano is 40 days sober following a stint at a Texas rehab ... and is now continuing to receive treatment thanks to the assistance of Lamar Odom.
A rep for Renee tells TMZ she's now focusing on trauma therapy at Lamar's wellness facility -- which aims to fight substance abuse, a cause near and dear to Lamar following his own near-fatal overdose in 2015.
A rep for Lamar says he actually reached out to Renee via IG when she made headlines for her rehab stay in November .
