Lamar Odom has checked into a rehabilitation facility near San Diego, Calif., according to E! News. The troubled former NBA star didn't fall off the wagon, according to the report, he just went in for a tune-up, E!'s source says: "It was his own decision. He wanted to work on his mental and physical health for the next chapter of his life. He has not fallen off the wagon, but he understands the importance of maintaining his sobriety."

Odom overdosed in a Nevada brothel in October 2015, which sent him into a coma and into a long recovery phase once he came-to. Of course Khloe Kardashian was by his side every step of the way but, as the family's reality show Keeping Up With the Kardashians has documented, Khloe has been ready to be cut loose from her responsibilities to Lamar for a while now. She wants to move on with her own life and find a man ... and she's certainly done that!

X17online got the EXCLUSIVE photos of Khloe and boyfriend Tristan Thompson as they touched down in LA early Sunday morning for a romantic weekend in Khloe's hometown. In fact, the two were probably celebrating Khloe being in the last phase of her divorce proceedings with Lamar.

Could the reality of losing Khloe have sent Lamar over the edge and seeking support???
