"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 ... telling her if she needed anything while in treatment, to just let him know.
Lamar immediately put the gears in motion ... connecting Renee with admissions for his facility -- and she checked in last Thursday after flying to Cali from Texas.
So far, so good ... Renee is loving the program and plans on staying for another 60+ days while working on her mental health, sobriety and physical health.
This isn't the first celeb backing she's had ... seeking assistance from "The Hills" star Jason Wahler's foundation, Red Songbird, which works with those struggling with substance abuse and trauma-related mental health issues.
