Lamar Odom collapsed early Sunday at Bootsy Bellows nightclub in West Hollywood, and his rep said heat and dehydration were to blame. 

The former Lakers and Clippers basketball player was caught on video, released by TMZ, seemingly out of it. Odom wound up sitting up in a booth with his eyes open after security staffers got the 6-foot-10 ex-athlete up from the floor. 

The man once married to Khloe Kardashian has a bad track record with losing consciousness: Two years ago, he went into a coma and nearly died after an overdose at a brothel in Nevada.

However, his rep said Odom was simply dehydrated Sunday after a workout the previous day.
