This is so sad.

Lamar Odom collapsed while partying at Bootsy Bellows nightclub on early Sunday morning, and TMZ got video of the whole thing! The troubled basketball star fell to the ground and security and patrons rushed to his side to help him regain his footing, and although he was conscious, he seemed pretty out of it!

The person who took the video told the news site that they personally witnessed the former Laker drinking alcohol for several hours before the incident, which would mean he has relapsed after a prolonged period of sobriety. The athlete went to rehab earlier this year, but lately he has been spotted at strip clubs and other questionable venues, leading to fears that he's fallen off the wagon.

This is especially worrisome, considering he almost died when he was found unconscious in a brothel in 2015. At the time, Khloe Kardashian nursed him back to health, but now she has moved on and is expecting a baby with boyfriend Tristan Thompson, so it's unlikely she's going to rush to his side to get him back on the right path.

Odom's rep told TMZ that he collapsed due to severe dehydration stemming from an intense workout earlier in the day, but that he's "doing great."

We'd like to believe that, but we just don't. We're terrified for Lam Lam and hope he gets the help he needs!
