Lamar Odom Calls the Whole Thing Off

TMZ has learned Lamar Odom has backed out of his bachelor party -- which Joe Francis and Khloe Kardashian's brother Rob were supposed to hold tonight.

Odom tells TMZ:

"I am extremely thankful to Joe Francis and Rob Kardashian, for agreeing to host my bachelor party this evening at Hollywood hot spot Les Deux.

I regret, I will have to cancel this event because I have now decided to have a private dinner with my teammates, a few close friends and of course Joe Francis and Rob Kardashian."
